Answer:
$3.80
Step-by-step explanation:
Given that:
One cup of lemonade is sold at 45 cents.
Total money made = $17.10
Number of cups of lemonade sold can be found by dividing the total money made with the sale price of one cup of lemonade.
Number of cups of lemonade sold = [tex]\frac{\$18.10}{45\ cents} = \frac{\$18.10}{\$0.45} =38[/tex]
For each cup sold, 10 cents are donated.
Total money donated = 38 [tex]\times[/tex] 10 = 380 cents = $3.80
Therefore, the answer is:
Total money donated by Mary is $3.80
