Question

Mrs. Rodriguez assigns 9 more homework problems to

her afternoon class than to her morning class. On
Tuesday, the morning class was assigned 19 homework
problems. Amanda is a student in the afternoon class.
She has already completed 11 homework problems.
How many more problems must she complete?

Answer 1

17 problems.

Explanation:

19 + 9 = 28

(Amanda is in the afternoon class, so she gets 9 more homework assignments than the morning class, which gets 19.)

28 - 11 = 17

(Amanda has already completed 11 homework problems.)

Answer 2

19+9=28
28-11=17
17 is your answer.
