Answer:
Percentage of mixture= [tex]7.5\%[/tex]
Step-by-step explanation:
Salt content in pounds= [tex]2.5[/tex] lb
[tex]1\ lb = 0.12\ gal[/tex]
Therefore salt content in gallons = [tex]2.5\times 0.12 = 0.3[/tex] gal
Water content in mixture = [tex]4[/tex] gal
Percentage of mixture= [tex]\frac{\ Salt\ Content}{Water\ Content}\times 100 = \frac{0.3}{4}\times 100=\frac{30}{4}=7.5\%[/tex]
