Question

a restaurant sells a family meal for $22 plus $2 per drink. Another restaurant sells a family meal for $25 plus $1.50 dollars per drink. how many drinks need to be purchased at each restaurant so the total cost for a meal and drinks is the same?

Answer 1

6 drinks

Explanation:

To find out how many drinks must be purchased for the meal to cost the same amount, we have to set the two expressions equal to each other

22 + 2x = 25 + 1.50x

0.50x + 22 = 25

0.50x = 3

x = 6

Then we can check our answers individually

22 + 2(6) = 34

25 + 1.50(6) = 34
