How much will I save on each box of soap? ** For each box of soap, I can save $16 x .25 = $<<16*.25=4>>4.
How much will I save on the 3 liters of chlorine? ** With the 3 liters of chlorine, I can save $2 x 3 = $<<3*2=6>>6.
How much will I save on the 5 boxes of soap? ** With the 5 boxes of soap, I can save $4 x 5 = $<<4*5=20>>20.
