Math Problem of the Week - Lower Elementary - Dec. 5, 2021 to Dec. 11, 2021

Lower Elementary: 

Question: Zachary sold books at a yard sale for 15 cents each and toys for $1 each. If he sells 6 books and 3 toys, how much money does Zachary make altogether?

Answer:  Zachary makes $3.90.

Solution:  Zachary earned 15¢, 6 times for the books. That’s 15, 30, 45, 60, 75, 90¢ for all 6 of the books. He earned $1.00, 3 times for the toys. That’s $3.00 for all 3 of the toys. So, altogether, Zachary earned $0.90 + $3.00 = $3.90.
