At the local ballpark, the team charges $5 for each ticket and expects to make $1,500 in consessions. The team must pay its players $2,200 and pay all other workers $1,500. Each fan gets a free bat that costs the team $3 per bat. How many tickets must be sold to break even?
A - 275 B - 1100. C - 2600 D - 440
Answers
Answer:
B - 1100 tickets
Step-by-step explanation:
Fixed costs appear to be ...
$2,200 +1,500 = $3,700
The amount of cost that is not covered by concession income is ...
$3,700 -1500 = $2,200 . . . . remaining cost
The contribution margin per ticket is apparently ...
$5 -3 = $2
So, the number of tickets that must be sold to cover the remaining cost is ...
$2200/($2/ticket) = 1100 tickets
revenue is 5 dollars a ticket plus 1400 dollars in concessions.
the cost for the players is 2000 dollars and the cost for the other workers is 1600.
each person who buys a tickets gets a free bat that costs 3 dollars each.
let x equal the number of people who buy a ticket.
revenue = 1400 + 5x.
that's the revenue from the concessions plus 5 dollars for each ticket sold.
cost = 3600 + 3x
that's 2000 for the players and 1600 for the workers and 3 dollars for each bat given away.
profit = revenue minus cost.
profit = 1400 + 5x - (3600 + 3x)
simplify to get:
profit = 1400 + 5x - 3600 - 3x.
combine like terms to get:
profit = -2200 + 2x.
to find the break even point, set profit equal to 0.
set p = 0 and the profit equation becomes:
0 = -2200 + 2x.
add 2200 to both sides of this equation to get:
2200 = 2x
divide both sides of this equation by 2 to get:
1100 = x
Select the equation that has a = 112 as its solution.
a−114=35
a+358=434
416+a=523
a×38=214
Answers
Answer:
none
Step-by-step explanation:
a-114=35 ⇒ a= 149
a+358=434⇒ a=76
416+a=523⇒ a=107
ax38=214⇒ a=5.63
The equation that has 112 as it's solution is not existing in the options.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given are four linear equations.
Check the solution of each equation.
a - 114 = 35
Adding both sides of the equation with 114,
⇒ a = 35 + 114 = 149
a + 358 = 434
Subtracting both sides of the equation with 358,
⇒ a = 434 - 358 = 76
416 + a = 523
Subtracting both sides of the equation with 416,
a = 523 - 416 = 107
a × 38 = 214
Dividing both sides of the equation with 38,
a = 214/38 = 5.63
Hence none of the equations have 112 as it's solution.

Billy and Karen are playing a billy and Karen are playing a game. They toss a coin that can land either heads or tails and a
spinner that can land on any of 8 equal regions. If a coin is tossed and the spinner is spun,
howmany possible outcomes are there?
Answers
The number of possible outcomes for both Billy and Karen = 32 possible outcomes.
A coin has head and tail and thus;
Number of possible outcomes of a coin toss = 2
Now, for the for the spinner, since there are 8 equal regions;
The number of possible outcomes of the spinner = 8
Now, since they are playing a game;
Number of possible outcomes for Billy for one toss of coin and one time of spinning the spinner = 8 × 2 = 16
Similarly;
Number of possible outcomes for Karen for one toss of coin and one time of spinning the spinner = 8 × 2 = 16
Therefore;
Total possible outcomes for both Karen and Billy = 16 + 16 = 32 possible outcomes.

which of the following represents an arithmetic sequence with a common difference of -8.5?
Answers
Answer:
C
Step-by-step explanation:
to have a common difference of -8.5, the sequence has to consistently go down by 8.5.
in the first one, y would go up by 2 every time x goes up by 1, so its not that one.
in the second one, it does go down by 8.5 the first time but the next time it goes down by 4.25, so it's not consistent.
in the third one, each time it goes down by 8.5 so this is the answer.
the fourth one also isn't correct because the graph shows that it is going up, so you know for sure it's not that one.

The constant of proportionality is the same as the slope for equations of the form y = kx.
To find the value of k, we divide the y over x values.
k = y/x = 12/8 = 1.5

k = y/x = 6/4 = 1.5
Either way the answer is 1.5

The function is given below.
N(x) = x² -2x + 2016
N represents the number of gang-related homicides across the country x years after 2017.
Then the number of gang-related homicides be 2051 will be given as,
N(2051 - 2017) = (2051 - 2017)² - 2(2051 - 2017) + 2016

Based on the information the number of people that will there after 20 years is: d.) 2.97 million.
Using this formula
P(t) = Population ×(1+ rate)^t
Where:
Population=2 million
rate=2%
time=20 years
Let plug in the formula
P(t) = 2×(1+.02)^20
P(t) = 2×(1.02)^20
P(t) = 2×1.485947
