taurant 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
(1073 + 1108 + x) / 3 = 1000 (2181 + x) / 3 = 1000 ....multiply both sides by 3 2181 + x = 1000 * 3 2181 + x = 3000 x = 3000 - 2181 x = 819 <== they would need to earn $ 819 on Sunday
