B.
Madison will reach her goal in 17 months.
C.
Madison will reach her goal in 18 months.
D.
It will take more than 18 months for Madison to reach her goal.

Answer 1

C

Explanation:

The inequality is

40m + 300 > 1,000

subtract 300 from both sides 40m > 700

divide both sides by 40 m > 700/40

(don't reverse the sign. 40 is (+)) m > 70/4

m > 17.5

The answer is C. Madison will not reach her goal in 17 months, but she will be there by the end of the 18th month.
