You start a bank account with $25. then, each week you deposit $15. how many weeks will it take to have $235 in the account?

a.14
b.17
c.17.3
d.10

14 weeks.  Here's how I got my answer :
$235 - $25.00 = $210.00
$15.00 x 14 = $210.00
$210.00+ $25.00 = $235.00
It couldn't hurt to get a few more answers with a variety of ways to solve the problem though.

Let us assume the number of weeks required = x
Initial amount of deposit = $25
Amount of money deposited each week = $15
Then
15x + 25 = 235
15x = 235 - 25
15x = 210
x = 14
From the above deduction, it can be easily assumed that the correct option among all the options given in the question is the first option or option "A".
