answer:

a

step-by-step explanation:

to find the intercepts, that is where the line crosses the x and y axes

• let x = 0, in the equation for y- intercept

• let y = 0, in the equation for x- intercept

x = 0 : - 15y = 60 ⇒ y = - 4 ← y- intercept

y = 0 : 3x = 60 ⇒ x = 20 ← x- intercept

0.85$ for 1 cups

1$ for 1/0.85 cups

55.25$ for [1/0.85]*55.25 = 55.25/0.85 = 65 cups
