Broderick Schmidt · 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?

Jonathon Sloan · 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$
