You can imagine dilution according to factors. The new total quantity of solution is 18 quarts. The baking soda is diluted by 10/18, and the soap is diluted by 8/18.

Baking soda: 4%2A%2810%2F18%29=4%2A%285%2F9%29=20%2F9=highlight%282%262%2F9%29 percent
Soap: 45%2A%288%2F18%29=45%2A%284%2F9%29=highlight%2820%29 percent
