Romashka [77]

Answer:

C. 6.67

Step-by-step explanation:

Given

Reserve Ratio (RR) = 15%

Required

Determine the simple deposit multiplier

Simple deposit multiplier (M) is calculated by taking the inverse of RR.

The following formula applies:

M = \frac{1}{RR}

Substitute 15% for RR

M = \frac{1}{15\%}

Convert 15% to decimal

M = \frac{1}{0.15}

M=6.67

<em>Hence, option C answers the question</em>
