Question

You earn $5.25 per hour. How much will you earn in 25 hours? (multiple choice)

(A) $207.20 (B) $129.50 (C) $131.25 (D) none of these

Answer 1

Explanation:

Look for keywords

when you see "per" that means theres a rate (something happens every unit of time)

To write a rate you divide whatever happens by whatever unit of time youre useing

In this example our rate is 15$ per hour which can be written as:

15$/1 hour (but we usually dont write it if theres a 1)

You can think of this as a regular fraction

`(15)/(1 \: hour) * 25 \: hour`

Here the hour will cancel and youre left with $
