Answer:

C. $750

Explanation:

With the given information in the problem, setting up a proportion with equivalent ratios (fractions) would be a good way to solve for the missing variable, or the amount that was in Mrs. Manning's savings account last month . Since we know that her current balance of $1170 is 156% of what she had last month we can set up the following proportion:


(156)/(100)=(1170)/(x) where 'x' is the amount from her savings last month, which would represent 100%.

Using cross-multiplication and division, we can solve for 'x':

(1170)(100) = 156x or 117000 = 156x

Divide both sides by 156:
(117000)/(156)=(156x)/(156)

Solve for 'x': x = $750 which is the amount in her last month's savings.
