The answer you are looking for is 40 hours. they gave you the answer in the statement above when they said he gets time-and-a-half for any hours beyond 40. So he only worked 40 regular pay hours and got 4 hours overtime for time-and-a-half.
B. I’m pretty sure. Since the arrow is pointing towards the S which is at the beginning.
A prime factor is a number with a greatest common factor of 1 and that number. Examples: 3,7,9,11
Percent change = (new number - old number)/(old number) * 100
percent change = (127 - 136)/(136) * 100
percent change = -6.62%
Since the percent change is negative it is a percent decrease.
Answer: 6.62% decrease.
