If a plane was for $3,950,000 then how many months do I have to make the bill $1 per month?

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
