Answer 1

To solve the question we have to write two different equations. I am going to do this step-by-step. Let x be the price of the magazine and y the price of the pizza. Thus:

The equation is:

$x+y=9.75_{}$

The next part is:

The equation is:

$y=2x$

To find the prices we can substitute the second equation on the first one:

$x\text{ + 2x = 9.75}$$3x\text{ = 9.75}$$x\text{ = 3.25}$

Thus:

$y\text{ = 2}\times3.25=6.5$

Hence the price of the pizza will be $6.5 and the price of the magazine will be $3.25.
