A liter of chlorine costs $10 and is now sold at 20% off. A box of soap that costs $16 is now sold at 25% off. How much will you save if you buy 3 liters of chlorine and 5 boxes of soap?
For each liter of chlorine, I can save $10 x .20 = $<T>multiply(10, 0.2)=2.0
For each box of soap, I can save $16 x .25 = $<T>multiply(16, 0.25)=4.0
With the 3 liters of chlorine, I can save $2 x 3 = $<T>multiply(3, 2)=6
With the 5 boxes of soap, I can save $4 x 5 = $<T>multiply(4, 5)=20
Therefore, I can save a total of $6 + $20 = $<T>add(6, 20)=26
