I went to

to buy tiles for my kitchen floor. I found that different color tiles were different prices. Here are the prices:

yellow tiles

$1

blue tiles $2

red tiles

$3

I only have $13 to spend and I need to find out what different combinations of the 3 colors I can make to spend all of my money. Can you help show some of them?

Use color tiles to help solve.

Example: 4 red and 1 yellow= $13

Challenge: What combinations could I make if I could buy green tiles for $4 each?
