Question
Jane has 30 gallons in her swimming pool. She pulls the plug and it is losing 2 gallons a minute.
When will she have 5 gallons left?
The answer posted is -2m+30=5
My answer is -2m+32=5
Isn't this a arithmetic sequence related question so the first number in the sequence should be 30; -2(1)+32
Thanks in advance.
