Anja buys a magazine and a pizza. She spends $9.75. The pizza costs twice the amount of the magazine. How much does the pizza cost?

Cost of the magazine and a pizza that was bought by Anja = $9.75

Let us assume the cost of the magazine bought by Anja = x dollars

Then

Cost of the pizza bought by Anja is = 2x dollars

Then

x + 2x = 9.75

3x = 9.75

x = 9.75/3

= 3.25 dollars

So

The cost of the pizza bought by Anja = 2x

= 2 * 3.25 dollars

= 6.50 dollars

From the above deduction we can easily conclude that the cost of the pizza bought by Anja is $6.50.
