Martin will earn $25 per hour at a new job. During training, he will earn $20 per hour. What percent of Martin's regular hourly rate will he earn during training?

He will earn 80% during training

Step-by-step explanation:

Lets take $25 as 100%

And take $20 as x

Using equivalent ratios, the equation would look like: $25:100% = $20:x

Next, turn them into fractions: $25 = $20

100%x

Cross multiply to get:

(25)x = $20×100%

The next step:

25x = $20×100%

2525

25 and 25 will cancel each other out leaving x, and 25 will divide 100% which will give you 4

Leaving it as:

x= 20×4%

x= 80%

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
