At the time of her grandson's birth, a grandmother deposits $ 3000 in an account that pays 3 % compounded monthly. What will be

GaryK [48]

Answer:

The value of the account will be $5,628

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=21\ years\\ P=\$3,000\\ r=3\%=3/100=0.03\\n=12$

substitute in the formula above

$A=3,000(1+\frac{0.03}{12})^{12*21}$

$A=3,000(1.0025)^{252}$

$A=\$5,628$

therefore

The value of the account will be $5,628

Last year, Sally had a gross profit margin of 68% in her hair salon. Her gross profit was $32,508.63. How much did Sally make in

Jlenok [28]

A business' profit margin is the ratio between the gross profit and net sales. It's ideal for a business to have a profit margin closest to 1. For the given situation, Sally has a gross profit of $32, 508.63 and a profit margin of 68% or 0.68. Thus, we have

$0.68 = \frac{32508.63}{sales}$
$sales = \frac{32508.63}{0.68} = 47806.81$

Therefore, the net sales earned by Sally's hair salon is $47, 806.81.

Answer: D. $ 47, 806.81
