Marcus is selling lemonade and peanuts.

Let X = lemonade

Let Y = peanuts

On Saturday, Marcus sold 5 more cups of lemonade than bags of peanuts

So, X = Y + 5 and he earned 7.05

Forming the equation.

[ (Y+5) * 0.75] + (Y*0.35) = 7.05

0.75Y + 3.75 + 0.35Y = 7.05

1.1Y = 7.05 - 3.75

1.1Y = 3.3

Y = 3

So the number of cups of lemonade is Y + 5 = 3 + 5 = 8

So there are 8 cups.
