Question

Which equation could be used to find the total amount earned, T, for working h hours at d dollars per hour?

Answer 1

Well, for each $h$ hour you work, you are going to earn $d$ dollars.

Given that we are keeping a constant rate of adding $d$ given the number of hours $h$, we can say that $T$ is the following:

$T = hd$

For example, working at 8 dollars per hour will get the following equation:

$T = 8h$

For every hour you work, you receive another 8. Thus, we are multiplying them together.

The final equation is T = hd.
