Here's a video where I explain how to solve these types of problems. If you play the video on full screen, it starts a bit blurry and then clears up nicely about 20 seconds in.
A correction: near the very end of the video, I say that $2.40-$0.85 is $0.55 when I should have said: $2.40-$1.85 is $0.55.
After watching the video, please solve the following problem:
Mrs. M has these coins:
5 quarters
4 dimes
2 nickels
I'd like to buy 4 giant chocolate fudge cupcakes (possibly to share with some people I like, but possibly to keep all for myself).
Each cupcake costs $0.75.
How much more money do I need to buy
