SOLUTION

GIVEN

Jennifer began a savings account. She initially put $100 in the account and then added $20 per month.

This can be modeled by the function

a(x) = 20x + 100

where x is the number of months and a(x) represents the total amount in the account.

TO DETERMINE

The amount Jennifer would have in her savings account after 24 months.

EVALUATION

Here the given function is

a(x) = 20x + 100

x = The number of months

a(x) = The total amount in the account.

We have to find the amount Jennifer would have in her savings account after 24 months.

Putting x = 24 we get

a(24) = ( 20 × 24 ) + 100

⇒ a(24) = 480 + 100

⇒ a(24) = 580

FINAL ANSWER

The amount Jennifer would have in her savings account after 24 months = $ 580
