Elementary school math problem

Question

Anja buys a pizza and a magazine. The pizza cost twice as much as the magazine. If Tanja spends $9.75 how much did the pizza cost

Answer 1

Since the pizza costs twice as much as the magazine, you could trade two magazines for a pizza.

The question said that one pizza and one magazine costs $9.75, so that would be the same as buying three magazines (if you traded the pizza for two magazines.)

$9.75 divided by 3 is $3.25 per magazine. The pizza would then be double the price of the magazine, or $6.50.

Answer 2

let x be the cost of the magazine

then 2x is the cost of the pizza

if you add the costs together you get $9.75

so x + 2x = $9.75

3x = $9.75

x = $3.25

so pizza cost = 2x = 2 * $3.25 = $6.50

Answer 3

The pizza cost is $3.25
