Answer:

240 lollipops

Step-by-step explanation:

Cherry probability=9/15=3/5=0.6=60%.

\frac{3}{5} =\frac{x}{400}

5x=1200

x=240

240 of the lollipops should be cherry-flavored.

You buy a sweater for $32, which is 30% off the original price. what was the original price?
Nataliya [291]

Answer:

45.71 = original price

Step-by-step explanation:

The sale price is equal to the original price minus the discount

sale price = original price - discount

The discount is equal to the original price  times the percent off

discount = original price * percent off

Substitute into the first equation

sale price = original price - original price * percent off

Factor out the original price

sale price = original price (1-percent off)

We know the sale price=32 and the discount = 30% = .3

32 = original price (1-.3)

32 = original price (.7)

Divide each side by .7

32/.7 = original price (.7)/.7

45.71 = original price

a. The function that models the situation is  F(t) = 48(1.08)ˣ

b. The price of the stock 6 years from now is $76.17

c. Find the graph in the attachment

d. I receive a dividend of $0.026.

<h3>a. Write a function f(t) that models the situation.</h3>

Since the stock price increases at a rate of 8% every year, and is initially $48, it follows exponential growth.

So, the current price F(t) = A(1 + r)^{t} where

  • A = price at current moment = $48,
  • r = rate of growth = 8% = 0.08 and
  • t = number of years

So,  F(t) = A(1 + r)^{t}

F(t) = 48(1 + 0.08)^{t} \\= 48(1.08)^{t}

So, the function that models the situation is F(t) = 48(1.08)ˣ

<h3>b. Determine the price of the stock 6 years from now?</h3>

The price of the stock 6 years from now is gotten when t = 6.

So,

F(t) = 48(1.08)^{t} \\= 48(1.08)^{6} \\= 48(1.5869)\\= 76.17

So, the price of the stock 6 years from now is $76.17

<h3>c. Sketch a graph of the price of the function vs time in years</h3>

Find the graph in the attachment

<h3>d. Bonus</h3>

Since every quarter, the company pays a dividend of 1.5 %, the rate per year would be r = 1.5 % ÷ 1/4 year = 1.5 % × 4 = 6 % per year.

Since they pay at a rate, r = 6 % = 0.06 of the stock price, F(t) as dividend.

After n years, the dividend is D = (r)ⁿF(t)

= (0.06)ⁿF(t)

So, D = (0.06)^{t}F(t) \\=  (0.06)^{t}[4.8(1.08)^{t}]

So, after 3 years when t = 3,

D = (0.06)^{t}[4.8(1.08)^{t}]\\D = (0.06)^{3}[4.8(1.08)^{3}]\\D = 0.000216 \times 48 \times 1.2597\\D = 0.013

Since there are 3 shares, the total dividend would be D' = 3D

= 3 × 0.013

= 0.026

So, i receive a dividend of $0.026
