Step-by-step explanation:

Given: The first group bought 6 slices of pizza and 4 soft drinks for $ 28.28.

The second group bought 5 slices of pizza and 4 soft drinks for $ 24.50.

As per question,

...(1)

...(2)

On subtracting equation 2 from 1 we have,

Hence, one slice of pizza costs  $3.78.

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
