Answer:

B

Step-by-step explanation:

9000-500 = 8500

8500 × (3/100) =255

8500 + 255 = 8755

8755 × (3/100) = 262.65

8755 + 262.65 = 9017.65

hence, the answer is B

Answer:

b) 2 years

Step-by-step explanation:

If you have $9000 in the saving account, and you take $500, you are left with:

$9000 - $500 = $8500

in one year you will have 3% more of the 8500 which is:

8500/100*3 = $255

so in one year the number on your savings account is:

8500 + 255 = $8755

and by the next year you will have 3% more of the 8755 which is:

8755/100*3 = $262.65

so in two years the number on your savings account is:

8755 + 262.65 = $9017.65

which is a little bit more than the $9000.

so it will take 2 years until the calance again reaches $9000
