If the required reserve ratio is 15 percent, the simple deposit multiplier is:_____

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>

Find the value of a1 for an infinite geometric series with S=12 and r=1/6

blondinia [14]

$S_n=a(1+r+\cdots+r^{n-1}+r^n)$
$rS_n=a(r+r^2+\cdots+r^n+r^{n+1})$
$(1-r)S_n=a(1-r^{n+1})$
$S_n=a\dfrac{1-r^{n+1}}{1-r}$

When $|r|$ , we have

$\displaystyle\lim_{n\to\infty}S_n=\dfrac a{1-r}$

as is the case here. Since $S=\lim\limits_{n\to\infty}S_n=12$ and $r=\dfrac16$ are given, we can find the first term $a$ immediately:

$12=\dfrac a{1-\frac16}\implies12=\dfrac65a\implies a=10$

A store sold 50 copies of a magazine for $150. Each copy of the magazine costs the same. Which equation and set of ordered pairs

Goryan [66]

Answer:

Option a. Y=3x

Step-by-step explanation:

Let us use cross multiplication method.

Let the cost of 1 magazine be x.

No. of copies Cost

1)50 $150

2)1 x

50x=150 x 1 equation(1)

x=150/50

x=$3

Now see equation (1),

150=50x

150=50 x 3

Here let us represent the cost as y and no. of copies as x.

Y=3x

Therefore, a. Y=3x is the right answer.

Thank you!
