Three plastic chairs cost as much as a portable table. Five plastic chairs cost $55. If Manny wants to buy one portable table and two chairs, how much will be left in his $100?
Each plastic chair costs $55/5 = $<T>divide(55, 5)=11.0
Two chairs cost $11 x 2 = $<T>multiply(11, 2)=22
A portable table costs $11 x 3 = $<T>multiply(11, 3)=33
Manny has to pay a total of $22 + $33 = $<T>add(22, 33)=55
Thus, Manny will be left with $100 - $55 = $<T>subtract(100, 55)=45
