Question

Darwin earns $11.75 per hour for gardening. If he worked 5 hours this Saturday, how much did he earn?

Answer 1

$58.75

Explanation:

Look at the terms (units) and set up the expression (equation) to give you the final answer you want.

We have dollars per hour, or $/h and we have hours. How can we combine those term to arrive at an answer in units of $ ? If we multiply $/h by h the h units "cancel out" (become = 1), leaving us with just $, which is what we want.

11.75 $/h * 5 h = 58.75 $ or $58.75
