Awater tank is currently three-quarters full. if 2500 gallons are drained, the tank will be one-third full. how many gallons of water can the tank hold when full?

We know from question that:

3/4 * volume - 1/3 * volume = 2500 Solving this equation for volume gives: Volume * ( 3/4 - 1/3 ) = 2500 Volume * ( 9/12 - 4/12) = 2500 Volume *

5/12 = 2500 Volume = 2500 / ( 5/12) Volume = 2500 * 12 / 5 = 500 * 12 = 6000 gallons.

Hope this helps!!

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
