Question 42406
The first thing you need to do is find out how must one patty would cost. 

So you divide 5.80 by 12. 

This gives you $0.48.

It asks for how many you could buy for $7.00

So divide $7.00 by $0.48

This gives you 14.58, well that tells you that could buy 14 hamburger patties. 

you can check with a calculator. If you round up and buy 15, you spend too much money. 

Hope this helps!
