<h2>
Answer:</h2>
x = (log₅7) - 8
<h2>
Explanation:</h2>
<em>Given;</em>
= 7
<em>Take log of both sides;</em>
log₁₀(
) = log₁₀7 -------------(ii)
<em>From the laws of logarithm remember that;</em>
logₐ xⁿ = n logₐ x
<em>Equation (ii) can then be written as;</em>
(x + 8)log₁₀5 = log₁₀7
<em>Divide both sides by log₁₀5</em>
(x + 8) =
-----------(iii)
<em>From the laws of logarithm, remember that;</em>

<em>Equation (iii) can thus be written as;</em>
(x + 8) = log₅7
x + 8 = log₅7
<em>Make x subject of the formula;</em>
x = (log₅7) - 8
Answer:
c
Explanation:
Reserve ratio is the percentage of deposits that is required of commercial banks to keep as reserves. The lower the ratio, the higher the increase in money supply
Money multiplier = 1 / reserve requirement
Money multiplier when reserve ratio is 10% = 1/10 = 0.1 = 10%
Money multiplier when reserve ratio is 20% =1/20 = 0.05 = 5%
there is a decrease of money multiplier from 5% to 10% when reserve ratio is increased from 10 percent to 20 percent
