That is running lemonade stand to earn money to donate to a pet shelter. He wants to at least $75. His supplies to make lemonade cost 15 if he charges 0.75 cents a cup how many cups does he need to sell to earn at least $75 which any quality represents the real world situation
The real-world situation can be represented by the equation:
(total earnings) - (cost of supplies) ≥ (desired amount)
Let's assume he sells "x" cups of lemonade.
The total earnings from selling "x" cups of lemonade would be equal to 0.75 * x.
The cost of supplies is given as $15.
So, the equation becomes:
0.75x - 15 ≥ 75
Let's simplify this equation:
0.75x ≥ 90
Divide both sides of the inequality by 0.75:
x ≥ 120
Therefore, he needs to sell at least 120 cups of lemonade to earn at least $75.
