On a store’s 100th anniversary, every person who enters gets a pin. Every fourth person gets a mug. Every tenth person gets perfume. Every 25th person gets an umbrella, and every 75th person gets a free dinner.

To find the shopper to get all the 5 gifts, we take LCM of 1, 4, 10, 25 and 75

Multiple of 1 : 1, 2, 3 , 4...............299, 300, 301, 302

Multiple of 4 : 4, 8, 12, 16, 20,............., 296, 300, 304........

Multiple of 10: 10, 20, 30, 40 ......................290, 300, 310.....

Multiple of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300....

Multiple of 75: 75, 150, 225, 300, .....

LCM of 1, 4, 10, 25, 75 is 300

So 300th shopper will be the first to get all 5 gifts.

Answer:

since M lies between point A and B , we came to know that,

M(4,6) =(x,y)

A(-2,-1)=(x1 ,y1)

B( _, _ )=(x2,y2)

Now using mid point formula,

x=x1×x2÷2 y=y1+y2÷2

so, point B is (10,13)

how much would you need to deposit in an account now in order to have 6000 in the account in 8 years. assume the account earns 6

Katen [24]

<h3>Answer:</h3>

$3,717.14

<h3>Step-by-step explanation:</h3>

Compound interest is the interest on the principal funding as well as the interest itself.

Compound Interest Formula

Compound interest can be solved by plugging known values into a formula.

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

In this formula, the variables stand for different values.

A = total amount
P = principal amount
r = rate as a decimal
n = times compounded per time period
t = time

So, for this question, we can plug in the values we are given and solve for P.

Identifying Known Values

First, let's find the exact numbers we are going to plug in.

6000 is the final amount we want, so A = 6000.
6%, the rate, is 0.06 as a decimal, so r = 0.06.
Since interest is compounded each month per year, n = 12.
The total time is 8 years, so t = 8.

Solving For P

Now we can plug all of these values in.

$6000=P(1+\frac{0.06}{12})^{12*8}$

First, simplify the values within the parentheses and in the exponent through arithmetic.

$6000 = P(1.005)^{96}$

Next, divide both sides by $1.005^{96}$

3717.14 ≈ P

*Note that the answer has been rounded to the nearest hundredth.

This means that you would need to deposit $3,717.14 into the account to have $6,000 in 8 years.
