One fish tank is being filled while another is being drained. The first fish tank has 175 liters of water and more water is being added at a rate of 7 liters per minute. The second fish tank has 550 liters of water and is being drained at 8 liters per minute. Which equation can be used to calculate how many minutes it will it take for the two tanks to have the same amount of water?

A: 175 + 7x - 550 - 8x
B: 175 + 7x - 550 + 8x
C: 8x - 7x = 550 + 175
D: 8x - 7x = 550 - 175

Please Help!!!

Respuesta :

it’s A, you start out with 175 liters then you add 7 liters times however many minutes has gone by. The second had 550 liters and but loses 8 times however many minutes has gone by for that.
