Question

You collect baseball and football cards. your uncle has an old collection of 360 cards that he gives you. the collection has more baseball cards than football cards in fact it is 30 more than twice a number of football cards how many of each are in your uncles collection

Answer 1

Let's call the number of football cards
`x`

Number of baseball cards =
`30 + 2x`

As the total number of cards is 360:


`x + 2x + 30 = 360 3x = 360 - 30 3x = 330 x = 110`

So there are 110 football cards

And there are 110*2 + 30 = 220 + 30 = 250 baseball cards
