Answer:
The pool has lost 441 gallons of water
Step-by-step explanation:
Multiply 7 (gallons last per minute) to 63 (the total amount of minutes) and you will get 441 gallons lost in total.
The amount of water is 30 gallons a minute
-6
-12 - (-6) = -12 + 6= -6
Your answer is 9.
53 x 2 = 106
106 + 20 = 126
126 / 14 = 9 !
