Answer:
20 ounces of cleaner
Step-by-step explanation:
Water 48 oz is 60% of unknown total. 60% = 3/5. Create equation and solve
48= 3x/5. 240= 3x. 80 = x
Total of water, bleach and cleaner is 80 ounces
60% + 15% = 75%
100% - 75%= 25% cleaner
.25 × 80 = 20 ounces

Hi dear,
log(x+3)-log10+logx+1=0
log(x+3)-1+logx+1=0
log(x+3)+logx=0
logx(x+3)=0
x(x+3)=10^0
x^2+3x-1=0
solve this equation that answers are:
X1= [ (13)^(1/2) - 3]/2
X1= [ (13)^(1/2) + 3]/2
