Question

You sell $89.50 worth of drinks at a concession stand by selling x small, 29 medium, and 12 large drinks. Write an equation you can
use to find the number of small drinks you sold.

Answer 1

89.50=(1.5*29)+(1.75*12)+x

Answer 2

Answer:

.5x + (.75×29) + 12 = 89.50

.5x + 21.75 + 12 = 89.50

.5x + 33.75 = 89.50

.5x = 89.50 - 33.75

.5x = 59.75

x = 59.75 ÷ .5

x = 111.5
