Question

Tammy brought 3 apps for $2.40. At the same price, how much would 10 apps cost​

Answer 1

The answer is $8.00.

Explanation:

First, you have to find how much for each app so you have to divide by 3 :

3 apps = $2.40

1 app = $2.40 ÷ 3

1 app = $0.80

Next, you have to multiply it by 10 :

1 app = $0.80

10 apps = $0.80 × 10

10 apps = $8.00
