Question

A magazine advertises that a subscription price if $29.99(for12 issues) represents a savings of 70% from the newsstand price.What is the price of one issue at the newsstand?

Answer 1

$29.99 is the final price.
"y" is the original price.
Subtract the savings from the original price to get the final price of $29.99.
70% = 70/100 = .70
y - (y x .70) = 29.99
y - .7y = 29.99
.3y = 29.99
.3y/.3 = 29.99/.3
y = 99.96667
y = $99.97 (rounded)

Answer 2

Answer:

$8.33

Step-by-step explanation:

$29.99 is the discounted price.  Since it is a 70% discount, this means it is 100%-70% = 30% of the original price.  30% = 30/100 = 0.3; this gives us the equation

0.3x = 29.99,

where x is the original price.

Solving this, we divide both sides by 0.3:

0.3x/0.3 = 29.99/0.3

x = 99.96666666 ≈ 99.97

This price is for 12 issues; this makes the price of 1 issue

99.97/12 = 8.330833333 ≈ $8.33.
