James decides to buy a new bed and bed frame.  The bed frame is $75 and the bed is 10 times that price.  He gets a deal for 20% off.  How much does he pay for everything?
The bed cost 75*10=$<T>multiply(75, 10)=750
So everything cost 750+75=$<T>add(750, 75)=825
He gets 825*.2=$<T>multiply(825, 0.2)=165.0 off
So that means he pays 825-165=$<T>subtract(825, 165)=660
