least 48 inches in height. Unfortunately, Derek is only 40 Inches in height, but he is growing an average of 1.2 inches per
month. Which inequality could be used to find m, the number of months that it would take for Derek to be eligible to ride the
roller coaster?
A. 40 + 1.2m > 48
B. 48 + 1.2m2 40
C. 40 + 1.2m < 48

Answer:

The correct option is A.

40 + 1.2m > 48

Step-by-step explanation:

Given that Derek is 40 inches in height, and a rollercoaster rider is required to be at least 48 inches. Since he is growing at an 1.2m per month, we want to find how many months, m it will take for him to reach that 48 inches height.

This, we need the height 1.2m to be added to 40 inches to give at least 48 inches.

1.2m + 40 ≥ 48

or

40 + 1.2m ≥ 48

This is the required equation.

Of all the options, option A is the best.

40 + 1.2m > 48
