Question

Enrique lives with his grandmother in a building for seniors. Earn additional money by commissioning some of your grandmother's neighbors. He charges $ 2 for every 1/4 hour work. It took 2/4 of an hour to go to the store for Mr. McGuire, 1 1/4 hours to deliver newspapers to the building manager and 3/4 of an hour to pick up groceries for Mrs. Schulz. Did Enrique earn money for a $ 18 DVD? Use models to explain your mathematical reasoning.

Answer 1

"He charges $ 2 for every 1/4 hour work." Multiply $2 and (1/4) by 4 and you'll get "$8/hr (eight dollars per hour of work).

Mr. McGuire: 2/4 hours times ($8 / hr) = how much money?

Building Manager: 1 1/4 hours times ($8 / hr) = how much money?

Mrs. Schulz: 3/4 hour time ($8 / hr) = how much money?

Add these 3 results together. Is the sum greater than or equal to $18?
or is it less than $18? Did Enrique earn enough to buy this CD?

Answer 2

yes, because it took him
2 4ths for the store which is 4$
then 1 and 1/4 for the newspaper which is 10$
then 3/4 for the groceries which is 6$

which then is 4 + 6 + 10 = 20
which is greater then 18$
