At a restaurant, when a customer buys 4 pretzels , the fifth pretzel is free. Soft pretzels cost $3.90 each. You order 12 soft pretzels . What is your mean cost per pretzel ?

($3.90)(12) - (2)($3.90) = 39.00

39.00/12 = 3.25 per pretzel

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
