Let's start by determining the profit they make from selling one cup of lemonade. The cost to make one cup is $0.10, and they sell it for $0.25. So the profit from one cup of lemonade is $0.25 - $0.10 = $0.15.
Let's assume they need to sell x cups of lemonade to make at least $10.00 more than they spend. The total profit they make from selling x cups of lemonade is given by the equation:
Profit = Number of cups sold x Profit per cup
In this case, the profit is $10.00 more than the total cost of making the cups of lemonade. The total cost of making x cups of lemonade is given by:
Cost = Number of cups sold x Cost per cup
Putting it all together, we have the equation:
Profit = Cost + $10.00
Number of cups sold x Profit per cup = Number of cups sold x Cost per cup + $10.00
Rearranging the equation to solve for the number of cups sold, we get:
Number of cups sold = ($10.00) / (Profit per cup - Cost per cup)
Substituting the values, we have:
Number of cups sold = ($10.00) / ($0.15 - $0.10)
Number of cups sold = ($10.00) / ($0.05)
Number of cups sold = 200
Therefore, Carolyn and Kim need to sell at least 200 cups of lemonade to collect $10.00 more than they spend.
