POD WEEK 8PROBLEM #2

By: Nora R.

Problem:What’s the greatest

amount of change you could have without being able to make change for a dollar?

Step #1-Since the question is asking for

the greatest amount I started with 3 quarters (75 cents)

I did this b/c I know that it would be easier to make change out of 2 quarters and if I had 4 quarters it

would already be 1 dollar.

Step #2Next, I added as many dimes as possible without being able to make change for a

dollar (4 dimes)

I did this b/c when you add four dimes (40 cents) and three quarters (75 cents)

you get $1.15, which if you tried to make change for a dollar with it wouldn’t work.

Step #3-I know I couldn’t use any nickels b/c a

nickel with two dimes would’ve equaled a quarter and that’s would’ve

given me change for a dollar

-But I noticed that I could add four pennies b/c if I added five pennies that would’ve equaled a nickel, but if I added just four pennies I still wouldn’t be able to make

change for a dollar

Last Step:I added up

75¢ (3 quarters), 40¢ (4 dimes), and 4¢ (4 pennies)

to get my answer.

ANSWER:The greatest amount of change you

could have without being able to make change for a dollar is:

$1.19

3 quarters

4 dimes4 pennies
