Question 304896
Amy has 4 quarters, 3 dimes and 2 pennies. Betty had 1 dime. Amy gave 3 of her coins to Betty. Amy now had 2 cents more than betty. Whata 3 coins did Amy give to betty?

Let x be the amount Amy gave to Betty.  Amy starts with $1.32 or 132 cents. Since Betty stated with 10 cents and needs 2 more cents to equal Amy's new amount we have:

132 - x = 10 + x + 2

2x = 132 - 10 - 2 
2x = 120
x = 60

Betty must have 2 quarters and one dime from Amy to equal 60 cents.
