Leonard and his brother Michael bought presents for their father. Leonard bought a wallet at $50 and two pairs of sneakers at $100 each pair, while Michael bought a backpack at $100 and two pairs of jeans at $50 each pair. How much did they spend in all?
Two pairs of sneakers cost 2 x $100 = $<T>multiply(2, 100)=200
So, Leonard spent $50 + $200 = $<T>add(50, 200)=250
Two pairs of jeans cost 2 x $50 = $<T>multiply(2, 50)=100
Thus, Michael spent $100 + $100 = $<T>add(100, 100)=200
Therefore, they spent a total of $250 + $200 = $<T>add(250, 200)=450 in all.
