Question

Jasmyn uses 42% of a gift card to buy groceries if she spent $67.20 on groceries, how much was on the gift card to begin with

Answer 1

The card was worth $160.

Explanation:

It is given that:

Percent of gift card used = 42%

Cost of groceries = $67.20

Let,

x be the total amount on gift card.

42% of x = 67.20

`(42)/(100)x=67.20`

0.42x = 67.20

`(0.42x)/(0.42)=(67.20)/(0.42)\\x=160`

Therefore,

The card was worth $160.
