He earned 32 for 4 hours, so you have 32/4.
Then you want to find the number of hours to make 80, so you have 80/h.
Set them to equal each other:
32/4 = 80/h
Now cross multiply:
(32 * h) / (4 *80)
Simplify:
32h = 320
Divide both sides by 32:
h = 320 / 32
h = 10
He will need to work 10 hours.

Step-by-step explanation:
You don't have any choices here, so we can just find the range of the answer. Then, you can select the correct answer.
The probability must be greater than 66.67%: P > 66.67% (or 2/3).
The chance of rain on Friday is 2/3. If it is more likely on Saturday, then it must be more than 2/3. 2/3 is about 66.67% percent.
First, multiply all fractions by 2.
3x-10/8x=52
Then multiply all sides by -10.
-30x + 8x = -520
-22x = -520
Divide both sides by -22.
x=23.6363
