Question

Wages. JoAnn works in the publicity office at the state university. She is paid $10 an hour for the first 35 hours she works each week and $15 an hour for every hour after that. If she makes $455 one week, how many hours did she work?

Answer 1

Well divide 435 by 10 so u can find if she worked 35 hrs.
43.5 hrs at $10 she did finish her $10 hours

455-350=105
105/15=15x/15
x=6

therefore she worked 35 hrs. +7 hrs.
she worked for 42 hours in total

Answer 2

Well, the first 35 hours she works is $10 per hour.
$35*10=350$

So that's 350 already.

Subtract 350 from 455.
$455-350=105$

Our goal is to get 105.

After 35 hours, each hour after that she gets paid $15.
How many times can 15 go into 105?

$105/15=7$

We're done!
Take the first 35 hours she worked and add the 7 we got from our last equation.

$35+7=42\ hours$

She worked 42 hours to get $455 in one week.
