Answer 4

First let's calculate her hourly wage

She makes $180 dollars in 20 hours

How much money does she make in 1 hour?

Just divide 180 / 20 = ??

Answer 5

9

Answer 6

So her hourly rate is $9 per hour

and she gets a 10% raise

so that means we're INCREASING her wage by 10%

what is

10% of 9?

basically

10% * 9 = ??

Answer 7

0.9??

Answer 8

Exactly!!

Now remember, how we said that we're increasing her salary by 10%?

that means you just add that 0.9 to the original 9

so her new salary is basically

9 + 0.9 = ??

Answer 9

9 . 9

Answer 10

You got it!

Another way to do it

since we're INCREASING by 10%

we know that 9 is the whole 100%

and we're increasing by 10%

we can just multiply 9 by (100% + 10%) or by 110%

so 110% = 110/100

and multiplying it with 9 would get you the same answer

Okay, thank you very much AZ.
