If Mr. Richards is making $18 an hour and gets a 12% raise. How much is his new hourly rate after his 12% raise?

$20.16

Step-by-step explanation:

First we need to find 12% of his current hourly rate, 12% is our decimal multiplier here so we use 0.12. In order to get 12% we need to multiply our decimal by $18 which is:

$18 × 0.12 = $2.16

Now let's add this 12% on top of his current hourly rate.

$18 + $2.16 = $20.16

And that's the final answer.

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

before simplifying this contains 4 terms

after simplifying

4y -15 + 4y^2
