Beth filled 31 jars with paint if each jar holds 1 pint of paint how many gallons of paint did beth use?

3.875 or 3 7/8  gallons of paint.

Step-by-step explanation:

There are 8 pints in a gallon.

31/8 = 3.875

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

boxplot e is the answer
