Question

A restaurant earns $1073 on Friday and $1108 on Saturday. Write and solve an equation to find the amount xx (in dollars) the restaurant needs to earn on Sunday to average $1000 per day over the three-day period. Write your equation so that the units on each side of the equation are dollars per day.

Answer 1

$819 to make an average 1,000 within 3 day period

Answer 2

(1073 + 1108 + x) / 3 = 1000
(2181 + x) / 3 = 1000
2181 + x = 1000 * 3
2181 + x = 3000
x = 3000 - 2181
x = 819 <=== the restaurant would need to make $ 819
