Katerina purchases 3 pots and 4 pans at the home goods store. Each pot costs $20. The total cost of Katerina's items is $100. If each pan is the same price, what is the cost of 2 pans?
The cost of the pots is 3 * $20 = $<T>multiply(3, 20)=60
The cost of 4 pans is $100 - $60 = $40
Since each pan is the same price, the cost of 1 pan is $40 / 4 = $<T>divide(40, 4)=10.0
The cost of 2 pans is $10 + $10 = $<T>add(10, 10)=20
