The discount store is having a big sale. paper towels are two rolls for 1 dollar. disposable diapers are 3 dollars a box if serena buys 2 rolls of paper towels and 2 boxes of diapers, how much change will she get from a 20-ddolla bill?

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
