Answer 2

you need to write an expense function and a revenue function

in general

expense = number of items * price that each item costs to make
and
revenue = number of items * price at which the item is sold

we are already given two variables, x = cups of lemonade and y = number of lemon bars

Answer 3

so revenue = 2x + 1.50y
expense = 0.25x + 0.2y

(lmk if you need help deriving these)

it says that the revenue was at least 500 and the expense was at most 100, and cups of lemonade is at least 150

therefore

2x + 1.50y >= 500
0.25x + 0.2y <=100
x >= 150

so you need to go through the choices one by one to see which one(s) fit all three equations
