2. Bella opens a savings account with $100 and the bank pays 1% monthly interest rate. How much money will Bella have after 12 months, if she does not deposit or draw an amount?

If someone answers this question they have to determine which equation is linear and which is nonlinear. Then, write a function that models the linear situation and then write 1 ordered pair that is the solution to the situation.

Answer 1

A linear function increases (or decreases) by a constant amount.

Does Jack the same number of cards each month?

50 = 30 + 2m, where m reprsents the number of months.'s

Bella's savings account sound linear also.

She gets 1% of $100 ($1) each month.

I = 100(0.01)(12)
