Question: Each week Jaime saves $50. Every two weeks she spends $46 of her savings on a nice lunch with her mum. How long will it take her to save $135?
Answer with step-by-step thinking: Jamie saves 50 * 2 = $100 every two weeks. After the lunch with her mum, Jamie saves $100 - $46 = $54 every two weeks. Jamie saves $54 / 2 = $27 per week. Jamie will need 135 / 27 = 5 weeks to save enough.
So the answer is 5.

Question: Rosie pays for a $.44 piece of candy with a $1 bill. If the cashier gives her the smallest number of coins possible as change, how many coins will Rosie get as change?
Answer with step-by-step thinking:
Rosie will get $1 - $.44 = $.56 in change. She will get 2 quarters to account for $.50 of the change. She will also get 1 nickel to account for $.05 of the change. Then, she will get 1 penny, to account for the last $.01 of the change. She will get 2 + 1 + 1 = 4 coins total.
So the answer is 4.
