Question

Carla has $300 in her bank account. Each time she goes to the ATM, she withdraws $20. Write a function for the amount of money left in her bank account. m = the bank account and x = a number of times she withdraws money.

Answer 1

The function for the amount of money left in Carla's bank account after withdrawing $20 each time is m(x) = 300 - 20x. If Carla withdraws money 5 times, there will be $200 left in her bank account.

Step-by-step explanation:

The function for the amount of money left in Carlo's bank account after withdrawing $20 each time can be represented as:

m(x) = 300 - 20x

Where:

• m(x) represents the amount of money left in her bank account
• x represents the number of times she withdraws money

For example, if Carla withdraws money 5 times, the function becomes:

m(5) = 300 - 20(5) = 300 - 100 = 200

Therefore, if Carla withdraws money 5 times, there will be $200 left in her bank account.

Answer 2

Okay. A function for this situation would be m = 300 - 20x. This is because Carla has $300 left in the bank account and she take out $20 per withdrawal.  As she withdraws more money from the bank, the total amount of money in there gets less and less.
