Question

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

Answer 1

Jennifer would have $580 in her account after 24 months

a(x) = 20x + 100

the above function is a linear function

A linear function is a function that has a single variable raised to the power of 1.

100 is the constant

20 increases by m

a(x) is the dependent variable. Its value depends on the amount deposited per month and the number of months

The amount she would have after 24 months =

20(24) + 100 = $580
