Question

Jean had $25.86 in her pocket. If shoes cost $7.50 a pair plus 10% of tax. How many pairs can she buy?

Answer 1

3 pairs

Explanation:

10% of 7.50 is 0.75. So one pair will cost $8.25. Now, 25.86/8.25 and you get 3 pairs

Answer 2

`\fbox {3 pairs}`

Explanation:

Cost of 3 pairs with tax :

⇒ 7.50 × 3

⇒ 22.50

* Adding tax *

⇒ 22.50 + 22.5 (0.1)

⇒ 22.50 + 2.25

⇒ 24.75

∴ Since 24.75 is less than 25.86, Jean can buy 3 pairs of shoes.
