Answer:

$9.60  or 48% increase

Step-by-step explanation:

The increase is the dollar change

29.60 - 20 = 9.60

The percent increase is, the new price minus the old price all over the old price

percent increase = (29.60 - 20)/ 20

                             = 9.60/20

                               = .48

                        Changing this to percent form

                               48% increase
