Deviation means possible distance in between sometimes 52,300-8,260 is 44,050 so that rules out b because 36,875 us belie 44,050 making the answer a but its always best to check anyways so 52,300+8,260 is 60,550 and 56,236 is in 60,550 so the answer is A

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

lapo4ka [179]

Answer:

The card was worth $160.

Step-by-step 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

$\frac{42}{100}x=67.20$

0.42x = 67.20

$\frac{0.42x}{0.42}=\frac{67.20}{0.42}\\x=160$

Therefore,

The card was worth $160.
