Question

A cell phone is on sale for 30% off. If the sale price is $239.89, what is the original price?

Answer 1

342.70

Explanation:

Since 100%-30%=70% our equation will be:

0.70x=239.89

x=original price

0.70x=239.89

/0.70 /0.70

Divide both sides by 0.70

x=342.7

$342.70

Answer 2

$342.7

Explanation:

Let the sale price be x.

So,

x - 30% of x = $239.89

x - 30/100*x = 239.89

(100x-30x)/100 = 239.89

70x = 239.89 *100

x = 23989/70

x = $342.7

sale price = $342.7
