Answer:

19.6

Step-by-step explanation:

The ratio of brown paint to white paint is, 5:7 or [tex]\frac{5}{7}[/tex] so if he bought 14 gallons of white paint we need to figure out:

[tex]\frac{5}{7} =\frac{14}{x}[/tex]

which we can as it only has one unknown:

5x=14×7

5x=98

x=19.6

So the answer is 19.6

Answer:

B. 19.6 gallons

5 Gallons of Brown ⇒ 7 Gallons of White

14 Gallons of Brown ⇒ x

x = 7 into 14 / 5

x = 98 / 5

x = 19.6
