Step-by-step explanation:
You've decided to buy a printer and have narrowed it down to two choices. The laser printer costs
$150 but the average cost of each page is just 1.5 cents. The other option is an inkjet printer, which
costs $30, but each page has an average cost of 6 cents. Determine the conditions (e.g. the number
of pages) where each printer is the better buy.
Answer:
The conditions are;
Where the number of paper printed = x (x ∈ Z)
For 0 ≤ x ≤ 2,666, It costs less to own and therefore it is better to buy the ink jet printer
For 2,666 < x ≤ ∞, it costs less to own and therefore it is better to buy the lase jet printer
Step-by-step explanation:
The given parameters are'
The cost of the laser printer = $150
The average cost of each page printed with the laser printer = 1.5 cents
The cost of the inkjet printer = $30
The average cost of each page printed with the inkjet printer = 6 cents
Let 'y', represent the total cost of ownership each printer and let 'x', represent the number of paper printed, we have;
For the laser printer, we have;
[tex]y_{laser \ jet}[/tex] = 150 + 0.015·x
For the ink jet printer, we have;
[tex]y_{ink\ jet}[/tex] = 30 + 0.06·x
Therefore, the initial cost of ownership of the ink jet printer is lesser than the initial cost of ownership of the laser jet printer
However, where the cost, 'y', of the laser jet printer and the ink jet printer are equal, we have;
[tex]y_{laser \ jet}[/tex] = [tex]y_{ink\ jet}[/tex]
∴ 150 + 0.015·x = 30 + 0.06·x
120 = 0.06·x - 0.015·x = 0.045·x
x = 120/0.045 = 2,666.[tex]\overline 6[/tex]
Therefore, given that the cost of ownership and the number of sheets printed is a straight line relationship, after printing 2,666.[tex]\overline 6[/tex] sheets or when 2,667 sheets are printed, the cost of ownership of the laser jet printer will become lesser than the cost of ownership of the ink jet printer
Therefore, the conditions where each printer is better to buy are;
For printing the number of papers in the range 0 ≤ x ≤ 2,666, the ink jet printer is better to buy
When the number of paper printed, 'x', is in the range, 2,666 < x ≤ ∞, the laser jet printer is better to buy.
We want to see when is better to buy which printer.
Printer 1 is better for 2667 pages or more.
Printer 2 is better for less than 2667 pages.
Printer 1 costs $150 pls 1.5 cents per page, so the cost for x pages is:
C₁(x) = $150 + $0.015*x
Printer 2 costs only $30, but each page costs 6 cents, so we have the cost:
C₂(x) = $30 + $0.06*x
First, we need to find the value of x such that the two costs are equal:
C₁(x) = C₂(x)
$150 + $0.015*x = $30 + $0.06*x
$150 - $30 = $0.06*x - $0.015*x
$120 = $0.045*x
$120/$0.045 = x = 2,666.67
Rounding to the next whole number we have x = 2,667
Then, if you plan to use less than x = 2,667, you should buy the second printer because it has a smaller y-intercept.
If you plan to use 2,667 or more, you should buy the first printer, because it has a smaller slope.

The linear function A(t)= 55t + 120 represents the amount, A, in Normans saving account where T represents time in weeks since he has been saving money for vacation what does a slope by 55 represent in the context of this scenario.
A. Norman will have saved enough to go on vacation after 55 weeks
B. Norman has been putting money into his savings account for five weeks
C. Norman has been deposing $55 each week into his savings account
D. Norman had $55 in his savings account before he started saving for a vacation
Answer:
C
Step-by-step explanation:
The reason it is C because if the answer was A, then the 55 would have to have been the T since the T represents time in weeks. If it was B, look at explanation for A. It is basically the same reason why. It is not D because if he already the 55 dollars in his savings then the 55 would have been the B of the equation which right now is 120. By process of elimination, your answer should be C. Also the fact that Norman was depositing 55 dollars EACH week is a big help.

There is a population of 350,000 bacteria in a colony. If the number of bacteria doubles every 163 minutes, what will the population be 652 minutes from now?
Answer:
228,200,000
Step-by-step explanation:
multiplication
Answer
5,600,000
Explanation
In 652 minutes, the bacteria will double 4 times.
163×4=652.
The starting population is 350,000.
After 163 minutes, the bacteria doubles once.
350,000×2 = 700,000
After another 163 minutes, the bacteria doubles again.
700,000×2 = 1,400,000
After another 163 minutes, the bacteria doubles again.
1,400,000×2 = 2,800,000
And finally, when 652 minutes past in total, the bacteria will be at 5,600,000.
2,800,000×2 = 5,600,000
So the population of the bacteria after 652 minutes will be 5,600,000.
Also, if you wanted to write an expression for this, it would be...
350,000×2^4
350,000 is multiplied by 2, 4 times.
Either way, you would get 5,600,000.

A health club has a monthly membership fee of $20 and charges an additional fee of $1.50 for every exercise class attended. Write an equation that represents the total cost, y, for a month in which a member attends x exercise classes
Answer:
y=1.50x+20
20 is the fixed price for each month, so that stays the same. It's the independent variable.
y=1.5x+20 is the equation that represents the total cost, y, for a month in which a member attends x exercise classes
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
A health club has a monthly membership fee of $20 and charges an additional fee of $1.50 for every exercise class attended.
We need to write an equation to represent this.
Total cost per person will be y.
Total cost is sum of membership fee and x be the the number of exercise classes.
y=1.5x+20
y equal to one point five times of x plus twenty.
Hence y=1.5x+20 is the equation that represents the total cost, y, for a month in which a member attends x exercise classes
