Answer: 5.4545 ounces
Step-by-step explanation:
Given the following :
Acid solution required = 75% acid solution
Let the number of ounces of 20% acid solution required = s
Then total ounces acid required can be expressed as :
=0.20s + 0.90 x 20
= 0.20s + 18
While the total ounces required is :
s + 20
Hence, (total ounces of acid / total ounces) = 75% acid solution
= (0.2 + 18) / (s + 20) = 0.75
= 0.2s + 18 = 0.75( s + 20)
0.2s + 18 = 0.75s + 15
18 - 15 = 0.75s - 0.2s
0.55s = 3
S = 3 / 0.55
= 5.4545 ounces
