mt-3m = t+1
(m-1)t = 3m+1
t = (3m+1)/(m-1)

In a recent student body election, Adam received 40 more than 40% of the votes. Brigitte received 40 less than 50% of the number

aniked [119]

Answer:

The total number of vote cast is 700

The maximum vote is of Adam, so He is winner

Step-by-step explanation:

Given as :

Let The total vote cast = v

The vote received by Adam = A = 40 + 40 % of v

I.e A = 40 + 0.4 × v ..............1

The vote received by Brigitte = B = 50 % of A - 40

I.e B = 0.5 × A - 40

or, B = 0.5 × ( 40 + 0.4 × v ) - 40

Or, B = 20 + 0.2 v - 40

∴ B = 0.2 v - 20 ........2

The vote received by Carl = C = 20 + 50 % of B

I.e C = 20 + 0.5 × ( 0.2 v - 20 )

or, C = 20 + 0.1 v - 10

∴ C = 10 + 0.1 v ...........3

The vote received by Diane = D = 180 votes

Now, According to question

The total vote cast = The vote received by Adam + The vote received by Brigitte + The vote received by Carl + The vote received by Diane

I.e v = A + B + C + D

Or, v = (40 + 0.4 v) + (0.2 v - 20) + (10 + 0.1 v) + 180

Or, v = (40 - 20 + 10 + 180) + ( 0.4 v + 0.2 v + 0.1 v )

Or, v = 210 + 0.7 v

Or . v - 0.7 v = 210

Or 0.3 v = 210

∴ v = $\frac{210}{0.3}$

I.e v = 700

So, Total number of vote cast = v = 700

Now, put the value of v in each equation

So , A = 40 + 0.4 × v = 40 + 0.4 × 700 = 320

B = 0.2 × v - 20 = 0.2 × 700 - 20 = 120

C = 10 + 0.25 × v = 10 + 0.1 × 700 = 80

So. Adam vote = 320

Brigitte vote = 120

Carl vote = 80

Diane vote = 180

So maximum vote is of Adam, so He is winner

Hence The total number of vote cast is 700

And The maximum vote is of Adam, so He is winner Answer

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%.
