Carolyn and Kim are selling lemonade this summer.

 It costs $0.10 to make each cup of lemonade.
 They are going to sell each cup of lemonade for $0.25.

What is the least number of cups of lemonade they need to sell in
order to collect $10.00 more than they spend? Show or explain your
work.

So the answer is X=67

for x cups of drink,

cost = .1x
revenue = .25x

.25x = .1x + 10
.15x = 10
x = 66.7 or x=67

To find the least number of cups of lemonade they need to sell in order to collect $10.00 more than they spend, we can set up an equation.

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.
