Arestaurant earns $1073 on friday and $1108 on saturday. write and solve the 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

I am guessing that you need an algebra equation so they are asking for an average of $1000 per day for 3 days which would be the $1000 times 3 and that has to equal the total earnings for Friday, Saturday, and Sunday. Friday and Saturday are known values and the unknown is (x) Sunday.

$1073 + 1108 + x = ($1000)*(3) equation

$2181 + x = $3000 simplify

$2181 + x - $2181 = $3000 - $2181  isolate x

x = $819 on Sunday to make the average of $3000 for 3 days
