Answer:

second answer: y = 5x + 120; $180

Explanation:

he starts with $120.

so, whatever else he does per month, there will always be the $120 starting amount to be added.

so, the third and the fourth answers are out.

then think : $5 every month.

that is how much after 2 months ? 2×5 = $10.

how much after 3 months ? 3×5 = $15.

so it has to be an equation that contains 5x (5 times the number of months).

combining both thoughts :

y = 5x + 120

now let's use x = 12 (for 12 months = 1 year).

5×12 + 120 = 60 + 120 = $180.

yes, it is that simple. no hidden "hocus pocus" is needed. just common sense.
