Given:

Cost of fish dinner = $10.95

selling price of fish dinner = $13.95.

To find:

The percent markup.

Solution:

We know that,

\text{Percent Markup}=\dfrac{\text{Price - Cost}}{\text{Cost}}\times 100

Using this formula, we get

\text{Percent Markup}=\dfrac{13.95-10.95}{10.95}\times 100

\text{Percent Markup}=\dfrac{3}{10.95}\times 100

\text{Percent Markup}=\dfrac{300}{10.95}

\text{Percent Markup}=27.39726

Round to the one decimal place.

\text{Percent Markup}\approx 27.4

Therefore, the markup is 27.4%.

ian invested an amount of money at 3% per annum compound interest. At the end of 2 years the value of the investment was £2652.2
Scorpion4ik [409]

Answer:

the amount of money Ian invested is P =  £2,500

Step-by-step explanation:

The standard formula for compound interest is given as;

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

Where;

A = final amount/value

P = initial amount/value (principal)

r = rate yearly

n = number of times compounded yearly.

t = time of investment in years

For this case, Given that;

A = £2652.25

t = 2 years

n = 1 (semiannually)

r = 3% = 0.03

substituting the given values into equation 1;

P = \frac{A}{(1+r/n)^{nt}} ...........1\\P = \frac{2652.25}{(1+0.03)^{2}} \\P = \frac{2652.25}{(1.03)^{2}} \\

P =  £2,500

the amount of money Ian invested is P =  £2,500

Please help me understand this equation
dangina [55]

Answer:

  D.  F(x) = (x +3)³ -2

Step-by-step explanation:

As with most multiple-choice math problems, you can try the different answers to see which is consistent with the information given in the problem. Here, that would mean you evaluate f(-3) to see if you get the value -2.

  A. (-3+2)³ -3 = -4 ≠ -2

  B. (-3 -3)³ -2 = -218 ≠ -2

  C. (-3 -2)³ -3 = -128 ≠ -2

 D. (-3 +3)³ -2 = -2 . . . . . . the correct choice

__

You are probably expected to understand that F(x) has been translated left 3 units and down 2 units from G(x). (The marked inflection point gives you the clue you need.) The transformation that translation does this is:

  F(x) = G(x -h) +k  . . . . .  G(x) translated by (h, k) units (right, up)

Translation left 3 and down 2 gives you (h, k) = (-3, -2), so ...

  F(x) = G(x -(-3)) -2 = G(x +3) -2

  F(x) = (x +3)³ -2
