Answer:

12(j+t) + 15 = c

Explanation:

So, lets go over what we know.

First off, for simplicity, lets consider Johnathan as J, and Trina as T.

We know that both J and T produce 12 dollars each per hour.

We know that J gets a extra 15 dollars.

We can think of the amount they produce each hour as the time they work in total, times the money they make a hour, which is 12.

We can think of this first part where the total time they work is (J + T)

The 12 dollars they get an hour can be though of as multiplying this sum: 12(J+T)

Finally, we know that J gets an extra 15 dollars.

This is not dependent on time, like the other variables, so we simply add it to the sum of what they make in the end:

12(J+T)+15

This looks like answer C.

Answer:

C

Hope this helps!
