Mary bought 5 boxes of drinks at $6 each box and 10 boxes of pizzas at $14 each box for her pizza party. She paid $200 for all the items. How much change did she get back?
Mary spent 5 x $6 = $<T>multiply(5, 6)=30 on drinks.
She spent 10 x $14 = $<T>multiply(10, 14)=140 on pizzas.
She spent a total amount of $30 + $140 = $<T>add(30, 140)=170
Therefore, Mary got a change of $200 - $170 = $<T>subtract(200, 170)=30 after paying all the items for her pizza party.
