First, determine what she earns per hour:
$43.20/8hr = $5.40/hr
Now that you know what her wage is, you need to determine how many hours she worked at her wage to have a $118.80 paycheck:
118.80/x = $5.40/hr
x = 22 hours.

22 Hours exactly ^_^
Sol'n: 43.20 / 8 = $5.4
it means $5.4 per hour is the payment of Josephine.
so, 118.80 / 5.4 = 22
therefore, she worked for 22 hours when paid $118.80

For 8 hours Joshephine was paid $43.20
So, for 1 hour she would be paid ($43.20/8) or $5.4
According to the question,
Joshephine would be paid $5.4 for working 1 hour
So, she would be paid $1 for working (1/5.4) hour
And, she would be paid $118.80 for working (118.80/5.4) or 22 hours.
The answer is 22 hours.

43.2 : 8 :: 118.8 : x
x = 118.8 x 8 / 43.2
= 22
She worked for 22 hours this week.
