A water tank holds 1,168 gallons but is leaking at a rate of 5 gallons per week. A second water tank holds 1,460 gallons but is leaking at a rate of 9 gallons per week. After how many weeks will the amount of water in the two tanks be the same?

it will take 73 weeks for the amount of water in the two tanks be the same.

Step-by-step explanation:

Let x represent the number of weeks it will take for the amount of water in the two tanks be the same.

A water tank holds 1,168 gallons but is leaking at a rate of 5 gallons per week. It means that the number of gallons that would be in the tank after x weeks is

1168 - 5x

A second water tank holds 1,460 gallons but is leaking at a rate of 9 gallons per week. It means that the number of gallons that would be in the tank after x weeks is

1460 - 9x

For the amount of water in both tanks to be the same, the number of weeks would be

1168 - 5x = 1460 - 9x

- 5x + 9x = 1460 - 1168

4x = 292

x = 292/4

x = 73

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
