Question

Terrance buys 6 bottles of sports drink. He has coupons for $0.55 off the regular price of each bottle. After using the coupons, the total cost of the sports drinks is $4.44. Which equation can be used to find the regular price p of a bottle of sports drink?

Answer 1

(4.44 + 0.55n) / n = p

(4.44 + 0.55 * 6) / 6 = p

(4.44 + 3.3) / 6 = p

(7.74) / 6 = p

1.29 = p

or

4.44 / 6 + 0.55 = p

Explanation:

n = number of bottles

p = 1.29
