To find the original cost of the shirt

Let the original cost be x

The markup percentage is 25%, which means the store is selling the shirt for 100% + 25% = 125% of the original cost.
So now the equation is
x + 25% of x = $40

We can write 25% as 0.25

So, x + 0.25x = $40

1.25x = $40

x = $40 / 1.25

x = $32

Therefore, the original cost of the shirt was $32.

So, the correct answer is option c)$32.

An ecosystem refers to a complex network of living organisms, their physical environment, and the interactions between them. It encompasses both the biotic (living) and abiotic (non-living) components of a specific geographical area or habitat. Ecosystems are characterized by the flow of energy and the cycling of matter, creating a dynamic balance and supporting the diverse forms of life within them.

Ecosystems can vary greatly in scale and can be found in diverse environments such as forests, oceans, grasslands, deserts, and even within our own urban landscapes. They can be as small as a pond or as large as an entire biome. Regardless of their size, all ecosystems share fundamental elements and processes.

Biotic components of an ecosystem include plants, animals, fungi, and microorganisms. These organisms interact with one another in various ways, forming intricate food chains and webs. For example, in a forest ecosystem, trees provide shelter and nutrients for birds, while birds, in turn, disperse seeds and control insect populations. Insects may pollinate flowers and decompose organic matter, contributing to nutrient cycling.

Abiotic components encompass the non-living factors that shape the ecosystem. These include sunlight, temperature, water availability, soil composition, air quality, and geological features. These abiotic factors influence the distribution and abundance of organisms within the ecosystem. For instance, the availability of water and temperature range determine the types of plants and animals that can survive in a desert ecosystem.

An example of an ecosystem is the coral reef. Coral reefs are vibrant marine ecosystems teeming with life. The corals, which are living organisms, form the framework of the reef. They provide shelter and food for a wide variety of fish, crustaceans, and other marine organisms. Algae and plants within the reef perform photosynthesis, converting sunlight into energy and oxygen. The coral reef ecosystem also includes abiotic factors such as water temperature, sunlight penetration, and nutrient availability, which influence the health and diversity of the ecosystem.

Ecosystems are highly interconnected and can be sensitive to disturbances. Human activities, such as pollution, deforestation, and climate change, can disrupt these delicate balances, affecting the health and functioning of ecosystems. Understanding and preserving ecosystems are crucial for maintaining biodiversity, providing ecosystem services, and ensuring the sustainability of our planet.

Women Empowerment: Unleashing the Potential of Women

Women empowerment is the process of enabling women to have control over their lives, make independent choices, and actively participate in all aspects of society. It seeks to dismantle gender inequalities and create a more equitable world where women can thrive and contribute their talents.

Women empowerment is not just a concept; it is a movement that has sparked transformative changes worldwide. One famous quote by Mahatma Gandhi encapsulates the essence of women empowerment: “If you want to know the real character of a society, look at how it treats its women.”

To understand the significance of women empowerment, we can turn to the inspiring story of Malala Yousafzai. Born in Pakistan, Malala fearlessly stood up against the Taliban’s oppressive regime that denied girls’ education. Despite facing grave threats, she championed for girls’ right to education through her blogs and public speaking.

Malala’s unwavering determination and courage garnered global attention, earning her the Nobel Peace Prize in 2014. Her journey serves as a powerful example of how one individual can ignite change and empower others. Malala continues to advocate for education as a fundamental right, inspiring millions of girls worldwide to pursue their dreams.

Women empowerment is not limited to the fight for education; it extends to economic independence and political participation. When women are economically empowered, they gain financial autonomy and decision-making power. This can be seen in the success stories of women entrepreneurs and leaders who have shattered glass ceilings and achieved remarkable milestones.

Political representation is equally crucial for women empowerment. Countries that prioritize women’s participation in decision-making processes benefit from more inclusive policies. Women’s voices and perspectives bring fresh insights and tackle issues that affect women’s rights, health, and overall well-being.

Women empowerment is a vital catalyst for social progress. Through education, economic empowerment, and political representation, women can break barriers, challenge stereotypes, and transform societies. Malala Yousafzai’s inspirational journey reminds us that every individual has the power to make a difference. By empowering women, we create a ripple effect that uplifts families, communities, and nations, leading to a more equitable and prosperous world for all.
