Korey’s operating expenses for last month would be $870

What is the gross profit margin?

The gross profit margin is a profitability raio. Profitability ratios measures the efficiency with which a company generates profit from its asset. Gross profit margin measures the return on sales.

Gross profit margin can be calculated by dividing the gross profit (difference between revenue and cost of goods sold) by revenue (Net sales). It could be expressed as a percentage by multiplying by 100.

Therefore, Gross profit margin = (gross profit ÷ net sales) x 100

Gross profit = $3,320

Net sales = $4,350

Gross profit margin = ($3,320÷$4,350) * 100

0.763 * 100 = 76.3%

4,350 - 3,320 = 1030

That would be 870 dollar.

Starbucks sells their coffee for $3.36 for 24 ounces
OR
Circle K sells their coffee for $2.40 for 16 ounces

Which is a better buy and by how much?

Answers

Answer:

Starbucks by 1 cent difference.

Step-by-step explanation:

Divide: 3.36 divided by 24 to find Starbucks. You get 14 cents per ounce

Divide: 2.40 divided by 16 to find Circle K. You get 15 cents per ounce

Compare: Starbucks is cheaper by 1 cent.

Answer:

starbucks is a better by because they each sell one ounce for the same price. from starbucks you get more ounces for the same price as you would at circle k

Step-by-step explanation:

starbucks: 24 / 336 = $0.07

1 ounce sells for about $0.07

circle k: 16 / 240 = 0.066 = (rounded) 0.07

1 ounce sells for about $0.07

Why do the roots of a quadratic equation have the opposite sign of the factors of a quadratic equation

Answers

Answer:

To find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

Step-by-step explanation:

Consider the provided information.

Roots of the equation is x-intercepts or zeros of the given equation.

So, By definition, the value of The y-coordinate is zero for points situated on the x-axis.

Thus, we can find the roots of a quadratic function, by putting f (x) = 0.

Now, let (x-a)(x-b) is the factor of any quadratic equation.

To find the roots of the quadratic function we will put our factor equal to 0.

[tex](x-a)(x-b)=0[/tex]

Now by the zero product property either x-a=0 or x-b=0

[tex]x-a=0[/tex] then [tex]x=a[/tex]

or

[tex]x-b=0[/tex]  then [tex]x=b[/tex]

So, we can say that to find the roots of the quadratic equation we set the factors of the quadratic equation equal to 0.

Henry has q5 lawns mowed out of total 60 lawns what percent of the laws does. Henry still have to mow

Answers

Answer:

Henry still has to mow 75% of the laws.

Step-by-step explanation:

It is given that Henry has 15 lawns mowed out of a total of 60 lawns.

We need to find: What percent of the lawns do Henry still have to mow?

Henry has 60 lawns in total.

He mowed 15 out of them.

The percentage of lawns mow = [tex]\frac{15}{60} \times 100=25 \%[/tex]

Henry mowed 25% of total lawns.

The percent of laws still have to mow = 100%-25%

The percent of laws still have to mow = 75%

Hence, Henry still has to mow 75% of the laws.

A movie theater sells adult tickets for $6 each. Senior citizens receive a discount of $3. One evening the theater sold 400 tickets and took in $2070 in revenue. How many tickets were sold to senior citizens?

Answers

Answer:

Number of senior citizen tickets sold= 110

Number of adults tickets sold= 290

Step-by-step explanation:

First, we need to establish a system of equations:

x= number of adults tickets

y= number of senior citizen tickets

x + y= 400

6x + 3y= 2,070

Now, we isolate x in one equation and substitute the value in the other:

x= 400 - y

6*(400 - y) + 3y = 2,070

2,400 - 6y + 3y = 2,070

330 = 3y

110 = y

Number of senior citizen tickets sold= 110

Number of adults tickets sold= 290

Prove:

290 + 110= 400

6*290 + 3*110= 2,070

Find angle x and y. Please show step by step process.

Answers

Answer:

x = 60, y = 25

Step-by-step explanation:

Δ ABC has 3 congruent sides and is equiangular, thus

the 3 angles are congruent, all 60°

x = 60

∠ ABC and ∠ CBD are adjacent and supplementary, sum to 180° , then

∠ CBD = 180° - 60° = 120°, so

y = 180 - (120 + 35) = 180 - 155 ← sum of angles in triangle

y = 25
