Can you please help me with this question

$1.22 per pair

The error is the contractor didnt take into account that there are 5 dozen gloves not 5 pairs of gloves. He calculated $73.20/5, which gave him $14.64.

Step-by-step explanation:

1 dozen = 12

5 dozen = 12 * 5 = 60

Therefore, you have 60 pairs of gloves.

He purchased all 60 pairs of gloves for $73.20.

73.20/60 = $1.22

This is how much one pair of gloves cost.

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
