For each liter of chlorine, I can save $10 x .20 = $<<10*.20=2>>2.
For each box of soap, I can save $16 x .25 = $<<16*.25=4>>4.
With the 3 liters of chlorine, I can save $2 x 3 = $<<3*2=6>>6.
With the 5 boxes of soap, I can save $4 x 5 = $<<4*5=20>>20.
Therefore, I can save a total of $6 + $20 = $<<6+20=26>>26.
