Karen works at Southern Technical College as a math teacher. She will be paid $900 for each credit hour she teaches. During the course of her first year of teaching, she would teach a total of 50 credit hours. The college expects her to work a minimum of 170 days (any less and her salary would be reduced) and 8 hours each day.

What is the minimum number of hours she is expected to work for the year?
Question 9 options:

A. 170
B. 50
C. 8,500
D. 1,360

Option D

1360

Step-by-step explanation:

The minimum stipulated number of days to work is given as 170 days and since each day one works for 8 hours then total hours per year on minimum side will be 170*8=1360 hours

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
