3 shirts + 2 pants. adding the cost of the shirts and the cost of the pants. so 3 * how much the shirts cost + 2 * how much the pants cost give you your total.
5/16 = n/80 bring 80 over to the other side to leave n alone. 80 then gets a multiplication sign in front of it. 5/16 x 80=n 5/16=0.3125 0.3125x80=25 n=25 hope this helps
