Question

A savings account compounds interest, at a rate of 25%, once a year. Eve puts $500 in the account as the principal. How can Eve set up a function to track the amount of money she has?

A(x) = 500(25)x where 25 is the interest rate

A(x) = 500(.25)x where .25 is the interest rate

A(x) = 500(1 + 25)x where 25 is the interest rate

A(x) = 500(1 + .25)x where .25 is the interest rate

Answer 3

A9x) = 500...
you have a rate of 25% one a year..

(.25)x...
I think it's 'B' because.
the 25% when you move it so it's not a percentage it becomes ".25" a decimal. and thats once a year which is "x"
