Did Enrique earn money for a $ 18 DVD? Use models to explain your mathematical reasoning.

    "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?

    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$
