Kane has $50.00. He goes to the supermarket and buys football boots and then he buys a soccer ball, which is half the price of the football boots.He then spends half of what she has left on a belt, leaving him with $15.00.

How much did the soccer ball cost?

How much did the football boots cost?

I started it like this:

Let x= price of football boots

Let 1/2(x) = price of soccer ball

the combined cost of soccer ball and football boots = x + 1/2(x)

Amount spent on the football boots and soccer ball :

$50-(

I am stuck

The text gives a clue that the price of the belt = $15

(How did they arrive at the conclusion that the price of the belt equals $15?)

Anyone has any ideas as to how I can move on?

Thanks
