dear mathcentral,
my name is belinda. please respond to my question. i'm in 5th grade. my teacher asked this question: what are two ways you can make 48 cents out of 6 coins? i could only figure out one way. please help.

thanks,
belinda

Hi Belinda
It's clearly a trick question. 3 pennies are needed and it's clear that there is a unique way to make 45 cents using 3 coins. How about giving somebody 2 dimes, a nickel, and a quarter and receiving 2 pennies in change?

Cheers
Chris
