x= The money she had in the account before the interest was paid.

(x-100)*.06+x=178.61

178.61+6=1.06x

184.61/1.06=x

x~$174.16

Guys pls show the workings!

We need some clarification!

First, is it 6% annual interest or monthly interest? Do you just get a 6% bonus no matter how long the money is in the account as long as it's there by the end of the month?

Second, show me the answer choices! This question takes about 1/3 the time to backsolve as it does to frontsolve (multiplication is way quicker than division), so answer choices are required to show the most efficient solution to the question.
