Question

A restaurant earns $1073 on Friday and $1108 on Saturday. Write and solve an equation to find the amount x (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

Step-by-step explanation:

F=1073

Sa=1108

then [F+Sa+Su]/3=1000

[F+Sa+Su]=1000*3

[F+Sa+Su]=3000

1073+1108+Su= 3000

2181+Su= 3000

Su=3000-2181

Su= 819
