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

Income of Friday + income of Saturday + Income of Sunday divided by 3 should be 1000 1073 +1108 + xx / 3= 1000 1073+ 1108 + xx = 1000 X 3 1073 + 1108 + xx = 3000 xx = 3000 – (1073 + 1108) xx = 3000 – 2181 xx = 819
