Three friends rented a kayak. it cost $4 per hour per person to rent the kayak, plus $2 for each life jacket, and $3 to park the car. it cost $57 in all. how many hours did they spend kayaking? write an equation and solve.

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

b.my answer is b.
