Olivia orders 24 cupcakes and a layer cake. The layer cake costs $16, and the total cost of the order is $52. What is the cost of each cupcake?​

Answers

Answer:

The total cost was $52. Subtracting out the cost of the layer cake ($16) leaves us with $36 to pay for the 24 cupcakes. This means that each cupcake must have cost $1.50 ( = $36 / 24 cupcakes ).

Step-by-step explanation:

Answer:

Below

Step-by-step explanation:

First let us create an equation for this problem

     (24 cupcakes)( $ of each cupcake) + ( $16 layer cake ) = $52

Let's say that C will represent the $ of each cupcake to make it easier

Solving it....

     24C + 16 = 52

     24C = 36

Divide both sides by 24

          C = 1.5

Therefore, each cupcake cost $1.5

We can check to see if this works....

     24(1.5) + 16 = total cost

            36 + 16 = 52, so this is correct

Hope that helped! Best of luck <3

Answer: 30x + 150

Step-by-step explanation:

Figure the amount of time worked in 4 weeks by 12 electrical wiring specialists who work 30 hours each week.​

Answers

Answer:

1440

Step-by-step explanation:

Let's say x = number of hours worked per week for 12 people. Now one worker works 30 hours a week so if you multiply 12 workers by 30 you will get how many hours 12 workers worked. so x = 12 • 30. 12 • 30 is 360. so x = 360 or for 1 week 12 workers worked 360 hours. now we need to find the amount of hours for 4 weeks. so we can do 4x or 4 times the amount of hours per one week. since x = 360. 4 • 360 = 1440.

Hi! I'm happy to help!

To solve for WX, we have to find the length of the part of the line that isn't XY. Since we know the full length of the line, we subtract the length of XY from WY to get WX:

100-89.6

10.4

The length of WX is 10.4 centimeters.

I hope this was helpful, keep learning :D

Answer: WX = 10.4 cm

Concept:

Here, we need to know the idea of the segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Solve:

Given information

XY = 89.6 cm

WY = 100 cm

Given expression deducted from the segment addition postulate

WX = WY - XY

Substitute values into the expression

WX = 100 - 89.6

Simplify by subtraction

WX = [tex]\boxed{10.4cm}[/tex]

Hope this helps!! :)

---> cereal A with grams will be multiplied by the sodium available in one gram of cereal A

----> The solution from the above equation would then be added to the cereal B with grams as well as its sodium content per grams.

6a + 8b ≤ 200

---> Cereal A's grams × Cereal A's calories + Cereal B's grams × Cereal B's calories is ≤ 150

so, 7a + 5b ≤ 150

An insurance company sells a homeowner's insurance policy that is $600 per year per policy. The insurance company predicts that the probability of having a home being damaged in the area it sells this policy is about 11,000. If the home is damaged, the insurance company expects to pay $400,000 to the homeowner. If the company were to sell 250 policies, how much money can it expect to gain or lose

Answers

Answer:

profit of $140,910

there is a missing number I will assume that the probability is 1 in 11,000

company expected revenue per policy = $600

companies expected expense = 400,000 * (1/11,000) = -36.36

profit per policy = $536.64

$536.64*250 = $140,910
