Question

Marcus and some friends want to buy fruit smoothies. The boys go to the shop that advertises a sale of 2 fruit smoothies for $5. Suppose Marcus and his friends but 8 smoothies.

Answer 1

$20

Explanation:

Given

Price of 2 smoothies = $5

We are to calculate the price of 8smoothies, say;

8 smoothies = $x

Divide both equations

2/8 = 5/x

Cross multiply

2x = 8×5

2x = 40

x = 20

Hence the price of 8 smoothies is $20
