Katie bought 4 sweaters that each cost the same amount and 1 skirt that cost $20 .the items she bought cost a total of $160 before tax was added.what was the cost of each sweater.
In order to solve this you first need to take $20 subtracted from 160 that leaves you with 140 next because she bought 4 sweaters you need to divide your remaining cash spent by 4 to get a total of $35 a sweater.
