An arena receives $1,700 per event for 12 concerts. If the costs for this sponsorship total $14,000, what is the profit margin f

miss Akunina [59]

Answer:

total profit margin for all 12 concert is $6,400.

profit margin for all one concert is $533.33

Step-by-step explanation:

Amount of money received for one event = $1700

Total no of concert = 12

Total money received for 12 event = Amount of money received for one event * Total no of concert

Total money received for 12 event = $1700 *12 = $20,400

Total cost of sponsorship = $14,000

Profit margin is the difference money invested and money earned.

here total investment is $14,000

Total money earned is $20,400

Therefore profit margin = money earned - total investment

= $20,400 - $14,000 = $6,400

Therefore total profit margin for all 12 concert is $6,400.

However to calculate profit margin for one concert we can simply divide the total profit margin for all 12 concert by no of concert (i.e 12)

profit margin for one concert = total profit margin for all 12 concert/total no of concert = $6,400/12 = $533.33

profit margin for all one concert is $533.33

Tell what whole number you can substitute for A in each list so the numbers are ordered from least to greatest. If there is none

hodyreva [135]

Answer: None

Step-by-step explanation:

If A=4, say for example, our list becomes: 3/4, 4/5, 75%.

This in decimal form becomes: 0.75, 0.8, 0.75 which is clearly not in ascending order.

If A =5, the list becomes 3/5, 5/5, 75% which clearly is 0.6, 1, 0.75 which is also not in ascending order.

For any value of A greater than 5, the second term A/5 is greater than 1 thus being less than the third term 0.75.

Therefore there is no whole number A that makes the list true.

Stefan sells Jin a bicycle for $137 and a helmet for $17. The total cost for Jin is 140% of what Stefan spent originally to buy

MatroZZZ [7]

Answer:

Stefan originally spent $110.

Stefan made a profit of $44.

Step-by-step explanation:

Given that:

Stefan sold the bike and helmet for $137 and $17

Total amount = 137+17 = $154

This is 140% of the price Stefan originally paid.

Let,

x be the original price paid by Stefan

140% of x = $154

$\frac{140}{100}x=154\\1.4x = 154\\\frac{1.4x}{1.4}=\frac{154}{1.4}\\x=110$

Therefore,

Stefan originally paid $110 for the bicycle and helmet.

Profit made by Stefan = 154-110 = $44

Hence,

Stefan originally spent $110.

Stefan made a profit of $44.

A 600g packet of biscuits costs $2.40. Calculate How much would a 200g packet cost?

sp2606 [1]

Answer:

$0.8

Step-by-step explanation:

There is a relation of direct proportion between quantity of biscuit and its cost.

Let 200 g biscuit will cost $x.

Therefore,

$\frac{600}{2.40} = \frac{200}{x} \\ \\ x = \frac{2.40 \times 200}{600} \\ \\ x = 0.4 \times 2 \\ \\ x = 0.8$
