Complete Question

A Chinese restaurant has the family special shown at right. What is the original average cost of the entrees if the discount is $2 per entree? ANY FOUR ENTREES FOR $20​

Answer:

$7

Step-by-step explanation:

From the question we are told that :

Any 4 entrees = $20,

And there is a discount of $2 per entree.

Let us represent the original average cost of entrees as = a

Hence, we have the algebraic expression

4(a - 2) = 20

4a - 8 = 20

4a = 20 + 8

4a = 28

Divide both sides by 4

4a/4 = 28/4

a = 7

Therefore, the original average cost of the entrees if the discount is $2 per entree is $7.
