$8.00 per ticket. You would like to have a profit of at least $600.
Step-by-step explanation:
$8.00 per ticket. You would like to have a profit of at least $600.
Answer:
your friend is not correct. You need to sell 90 tickets
Step-by-step explanation:
75 tickets X 8 = 600 ( remember you need 120 extra to pay supplies cost, so you need to sell 90 tickets and the costs is $ 8 per tickets)
let's say now.
90 tickets X 8 = 720.
720- 120= 600

Write another ratio that’s is equilevent too.4:6 and how do u know that your new ratio is equivelant too 4:6
Answers
Answer:
8:12
Step-by-step explanation:
Another ratio that is equivalent to 4:6 would be 8:12;
To find another ratio equivalent to another, simply find the multiples of the numbers that make up the ratio.
Using 2 as multiplier;
2 ( 4 : 6) = 8 : 12
I am sure of this because when we reduce both ratio to their lowest term, we get the same value;
4: 6 8: 12

elasticity of demand? show your work
Answers
Answer:
-30
Step-by-step explanation:
10 - 30 is not possible they owe
The value of price elasticity of demand is -4.
The price elasticity of demand refers to how a particular good responds as a result of a change in the price. In this case, the price elasticity of demand is calculated as:
= Percentage change in quantity/ Percentage change in price.
Since a 10% increase in price leads to a 40% decrease in quantity demanded, the price elasticity will be:
= - 40% / 10%
= -4.

Devante invests $4000 in two different accounts. The first account paid 6 %, the second account paid 11 % in interest. At the end of the first year he had earned $320 in interest. How much was in each account?
$
at 6 %
$
at 11 %
Answers
Answer:
Let x represent the amount of $ in the 4% account and y in the 2% account.
Then x + y = $4000 (total savings).
Interest at 4% would be x*0.04*1 = 0.04x, and
Interest at 2% would be y*0.02*1 = 0.02y.
Then 0.04x + 0.02y = $140 interest, total.
We must solve this system of linear equations.
Mult. 0.04x + 0.02y = $140 by 100 to remove the fractions:
4x + 2y = $14000 We already know that x + y = $4000, so y = $4000-x.
Then 4x + 2y = $14000 becomes 4x + 2($4000-X) = $56000.
Simplifying, 4x + $8000 - 2x = 14000.
2x = $6000
x = $3000 at 4%
y = $1000 at 2%

You would like to make a nutritious meal of eggs, edamame, and elbow macaroni. The meal should provide at least 40 g of carbohydrates, at least 20 g of protein, and no more than 50 g of fat. An egg (one serving) contains 2 g of carbohydrates, 17 g of protein, and 14 g of fat. A serving of edamame contains 12 g of carbohydrates, 12 g of protein, and 6 g of fat. A serving of elbow macaroni contains 43 g of carbohydrates, 8 g of protein, and 1 g of fat. An egg costs $2, a serving of edamame costs $5, and a serving of elbow macaroni costs $3. Formulate a linear optimization model that could be used to determine the number of servings of egg, edamame, and elbow macaroni that should be in the meal in order to meet the nutrition requirements at minimal cost. (You don’t need to find the optimal solution to the model you formulate) ======== In your response please - define decision variables with NUN (Name, Unit, Notation) (e.g. Let E be the number of eggs in the meal) Then provide the mathematical model for the LP problem. - objective function - constraints
Answers
Answer:
2x + 12y + 43 ≥ 40
17x + 12y + 8z ≥ 20
14x + 6y + z ≤ 50
x ≥ 0
y ≥ 0
z ≥ 0
Step-by-step explanation:
given:
Cost Eggs = $2
Cost of edema = $5
cost of elbow Macaroni = $3
Lets eggs = x,
edamame = y
elbow macaroni = z
TC = 2x+5y+3z
Therefore;
2x + 12y + 43 ≥ 40
17x + 12y + 8z ≥ 20
14x + 6y + z ≤ 50
x ≥ 0
y ≥ 0
z ≥ 0
the first objective is to make sure the total cost is subject to the required nutritional requirements.
So the total cost function (TC) is denoted by the number of servings multiplied for each costs. Eggs cost $2, edamame $5, and macaroni $3.
The problem subjects that each meal contains at least 40g of carbohydrates (this is the condition).
to get this we need to add what each meal component adds to the total, eggs add 2g of carbs, edamame 12g, and macaroni 43g.
Same should be done for protein, we require at least 20 grams of protein, Eggs add 17g, edamame adds 12g, and macaroni adds 8g.
and lastly we don't want more than 50 grams of fat, Eggs add 14g, edamame add 6g and macaroni 1g.
