Giovanni wants to buy shirts that cost $19.40 each and sweaters that cost $24.80 each. An 8% sales tax will be applied to the entire purchase. If Giovanni buys 2 shirts, which equation relates the number of sweaters purchased, p, and the total cost in dollars, y?

• 1.08(38.80 + 24.80p) = y

• 38.80 + 24.80p = 0.92y

• 38.80 + 24.80p = 1.08y

• 0.92(38.80 + 24.80p) = y
