Ali is a baker. Leila ordered 3 chocolate cakes for $12 each and 6 strawberry cakes for $22 each.  How much should Leila pay Ali?
For the chocolate cakes: Leila should pay: 12 * 3 = $<T>multiply(12, 3)=36
For the strawberry cakes: Leila should pay: 22 * 6 = $<T>multiply(22, 6)=132
Combining the chocolate cakes and strawberry cakes, Leila should pay: 36 +132 = $<T>add(36, 132)=168
