He Sun bought 3 skirts for k dollars each and a jacket that costs 5 times as much as each skirt. She spent a total of 280 how much did the jacket cost?

Steps:According to the given information, we have:

3*s+5*s=280 (we already know how much she spent which is $280 we also know she brought 3 skirts and the jacket being 5 times as the skirt)

we see like terms of 3*s+5*s= 8s

8s=280 (now divide 280 by 8 which is 35)

that means each skirt is $35 now to find for the jacket all we do is 35*5 which gives up $175
