Candy bars are sold in a local store for 60 cents each. The factory has 1000 in fixed costs plus 10 cents additional expense for
pochemuha

Answer:

2000 candy bars sold

$1200 in revenue

Step-by-step explanation:

Terms we need to know:

<u>Cost</u> "C": money needed/used to make the product (factory cost and candy bar expenses)

<u>Revenue</u> "R": money earned from selling the product (candy bars sold in a local store)

<u>Profit</u> "P": money left over after revenue is used to pay costs

<u>Break-even point</u> : when there is no profit (the profit is 0), what is the total revenue and number of items sold?

Create equations for the question:

State your variables.

let 'c' be the number of candy bars sold

R(c) = 0.6c                    Candy bars sell for 60 cents each

C(c) = 0.1c + 1000          10 cents expense per candy bar and factory cost

P(c) = 0          When profit is 0, we are looking to break even

Profit = Revenue - Cost

P(c) = R(c) - C(c)             Substitute the expressions above

P(c) = 0.6c - (0.1c + 1000)

Simplify this equation first. Use the rule for subtracting binomials, where you change the positive/negative for each number inside the brackets.

P(c) = 0.6c - (0.1c + 1000)    Positive in brackets, negative when taken out

P(c) = 0.6c - 0.1c - 1000             Combine like terms

P(c) = 0.5c - 1000            General equation for this problem

0 = 0.5c - 1000                 Remember profit should be 0

<u>Isolate "c"</u> to find how many candy bars made will result in the break-even point.

0 + 1000 = 0.5c - 1000 + 1000        Add 1000 to both sides

1000 = 0.5c

1000/0.5 = 0.5c/0.5             Divide both sides by 0.5

2000 = c          Answer

c = 2000       Variable on left side for standard formatting

Now to find the revenue at the break-even point.

Go back to the revenue equation for this question. Substitute when "c" is 2000.

R(c) = 0.6c

R(2000) = 0.6(2000)        Multiply

R(2000) = 1200              Revenue at break even point

Therefore the break-even point is when 2000 candy bars are sold, which would provide $1200 in revenue.

(8,15) (-14,-3)<br>find the slope
ss7ja [257]

The slope is 9/11 because if you use the formula (change in y)/(change in x), you would get -18/-22 and then if it were to be simplified, it would be 9/11

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

Total books borrowed = 8+4 = 12

No. of non - fiction books = 7

No. of fiction books = 12 -7

                                    = 5
