Answer 2

The cost of 3 jackets =$69.75

Explanation:

Use the given table

For 2 jackets, the cost is $46.50

For 1 jacket , the cost is
`(46.50)/(2) = 23.25`

For 5 jackets, the cost is $116.25

For 1 jacket, the cost is
`(116.25)/(5) = 23.25`

So the cost of 1 jacket = $23.25

The cost of 3 jackets = 23.25* 3= $69.75
