Question

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?

Answer 1

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.
