During a sale at a store, you buy 3 sweatshirts and two pairs of sweatpants for 85.50. Later you buy 3 more sweatshirts and 4 more pairs of sweatpants for 123.00. WHat is the sale price of each sweatshirt and each pair of sweatpants? How did you get the answer what formula
no formula -- just write down the facts:
If pants cost p and shirts cost s, then
3s+2p = 85.50
3s+4p = 123.00
You can now solve for s and p.
