I think the answer would be 24 but im not 100% sure
Let L represent the number of cups of lemonade that Marcus sold. Then his revenue can be described by ...
0.75L + 0.35(L -5) = 7.05
1.10L -1.75 = 7.05 . . . . . . . . . . eliminate parentheses
1.10L = 8.80 . . . . . . . . . . . . . . .add 1.75
L = 8 . . . . . . . . . . . . . . . . . . . . .divide by 1.10
Marcus sold 8 cups of lemonade on Saturday.
We are given to understand as per the problem that one must save 10% of their take home pay.
Reggie's take home pay is $2,340 per month
As per the rule Reggie must save 10% of 2,340 per month = 0.10*2,340 = $234 per month
Since we need to know the savings in a year, we have to multiply the monthly savings by 12 since there are 12 months a year
Minimum amount per year that he should save = $234 *12 = $2,808
Minimum amount per year that he should save = $2,808
