Barney's part time job pays $8.75 an hour. He is needs to have at least $577.50 saved for books this fall. Write an inequality to determine how many hours he needs to work.

577.50/8.75=X      

X= 66

Barney needs to work 66 hours to have enough money to pay for his books.

Hope I helped :)

Step-by-step explanation: I divided 577.50 by 8.75 to get my answer.

answer: the common difference is -0.10

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
