Oliver has 10 $20 and 3 $5 bills. William has 15 $10 and 4 $5 bills. How much more money does Oliver have than William?
Oliver's $20 bills amount to $20 x 10 = $<T>multiply(20, 10)=200
Oliver's $5 bills amount to $5 x 3 = $<T>multiply(5, 3)=15
So, Oliver has a total of $200 + $15 = $<T>add(200, 15)=215
William's $10 bills amount to $10 x 15 = $<T>multiply(10, 15)=150
William's $5 bills amount to $5 x 4 = $<T>multiply(5, 4)=20
So, William has a total of $150 + $20 = $<T>add(150, 20)=170
Therefore, Oliver has $215 - $170 = $<T>subtract(215, 170)=45 more than William.
