Question 13 • Financial Math

An investor has $⁢108,000 in an investment account and is going to make an additional deposit. She would like the ratio of the deposit, x , to the total investment to be (1)/(12) Which equation can she use to find the amount she needs to deposit to meet her goal?

Answer
A
112=x108,000 + x
B
1 over 12 is equal to the fraction with numerator x and denominator 108 comma 000
C
1 over 12 is equal to the fraction with numerator 108 comma 000 and denominator x
D
112=108,000 + xx

Explanation

The deposit is x, and after depositing it, the total investment will be $108,000 + x. Since the ratio of the deposit to the total must be 1/12, the equation is 1/12 = x/(108,000 + x). Choice A gives this relationship; using $108,000 alone as the denominator would leave out the deposit from the total.
