Answer:

a) 3600 - 400M

b) 3600 - 400M = 2000

c) 3600 = Initial balance

400M = Amount deducted in M months

2000 = Amount remaining in the account

Explanations:

The initial balance of the account = $3600

Amount removed from the account monthly = $400

Let the number of months be represented by M

a) the expression representing the amount in her account will be:

3600 - 400M

b) Amount remaining in the account = $2000

The equation whose solution is the number of months, M, it takes for the account balance to reach $2000 will be:

3600 - 400M = 2000

c) What each part of the equation represents:

3600 = Initial balance

400M = Amount deducted in M months

2000 = Amount remaining in the account
