Math Problem of the Week - Upper Elementary - Jan. 16, 2022 to Jan. 22, 2022

Upper Elementary: 

Question: William used to drink 6 cans of soda per day, but he decided to replace his soda with bottled water. If a can of soda costs $0.85 and a bottle of water costs $0.75, then how much money does William save each week by swapping from soda to water?

Answer: $4.20

Solution: Each soda costs $0.10 more than a bottle of water. So, each day, William saves $0.10 x 6 = $0.60. In a week, he saves $0.60 x 7 = $4.20
