Question

A checking account is set up with an initial balance of $3600, and $400 is removed from the account each month for rent (no other transactions occur on the account).a. create an expression representing the amount in her account .b. write an equation whose solution is the number of months, M, it takes for the account balance to reach $2000.c. what does each part of your equation represent?

Answer 1

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
