Answer:

1.) x=3

2.)x=10

Step-by-step explanation:

for the first problem you would add 1 to both sides, and you would get 5x=15, then you would divide both sides by by 5 to get x by itself. 5x/5=x and 15/5=3, so x=3. you can also plug it in. 5(3)-1=14

for the second one you wpuld subtract 15 from both sides, and you would get 3x=30. divide both sides by 3 which is x=10. plug it in, 15+3(10)=45.

At the beginning of January, Kesia Records paid $148,950 to acquire the exclusive rights to a new album. It costs them $1.13 to
ale4655 [162]

Answer:

d. May

Step-by-step explanation:

To find when Kesia records got to break even, we first need to find how much they made total per month.

Now we need to first find how much they made on January.

The production cost of January will be:

Production cost = 5486 x 1.13

Production cost = $6199.18

Now that we know the production cost, we need to solve first for the total revenue.

Total Sales Revenue = 5486 x 9.75

Total Sales Revenue = $53488.50

Now that we have both the revenue and the production cost, we need can find how much profit by:

Profit = Total Sales Revenue - Production cost - Overhead

Profit = 53488.50 - 6199.18 - 27714

Profit = $19575.32

So they made a profit of $19575.32 by the end of January.

Now we move on to the other months.

Production cost = 8191 x 1.13

Production cost = $9255.83

Total Sales Revenue = 8191 x 9.75

Total Sales Revenue = $79862.25

Profit = 79862.25 - 9255.83 - 21689

Profit = $48917.42

Now that we have the profit for 2 months, we simply add them together.

Current Value = 19575.32 + 48917.42

Current Value = 68492.74

By doing the same process with the rest of the months, we get:

Refer to Image.

We can see in the image that by May they reach a total profit of $149897.77.

Since Kesia records paid $148950, the company got to break even at the month of May.
