I have no idea what this question is, any ideas?

Answers

Answer 1
Answer: What this is asking is for you to plug values into the following function:f(x)=(3x-8)/(6x)

Since the question is asking you to find f(3)-f(1), this is how you work it out:
You take the function;
f(x)=(3x-8)/(6x)
And plug the numbers indicated in for x;
f(x)=(3x-8)/(6x)\nf(3)=(3(3)-8)/(6(3))\nf(3)=(9-8)/(18)\nf(3)=(1)/(18)\n\nf(1)=(3(1)-8)/(6(1))\nf(1)=(3-8)/(6)\nf(1)=(-5)/(6)\n\nNow\ what\ you\ do\ is\ you\ subract\ f(3)\ and\ f(1).\nf(3)-f(1)\nf(3)-f(1)=(1)/(18)-(-5)/(6)\nf(3)-f(1)=(1)/(18)-(-15)/(18)\nf(3)-f(1)=(1+15)/(18)\nf(3)-f(1)=(16)/(18)=(8)/(9)
So the answer to f(3) - f(1) = (8)/(9)

Esteban bought a new stove for $986 on his credit card. He used the stove for eleven years before replacing it. The stove cost him an average of $0.14 per day in electricity. Esteban had preventive maintenance done on the stove, costing $24.25 each year for the eleven years. Esteban’s credit card has an APR of 9.26%, compounded monthly. He paid off his balance by making identical monthly payments for five years. Sales tax in Esteban’s area is 8.22%. Assuming that Esteban made no other purchases or payments with his credit card, what was the lifetime total cost of the stove? (Assume that two of the years Esteban had the stove were leap years, and round all dollar values to the nearest cent.) a. $2,534.57 b. $2,166.53 c. $2,234.23 d. $2,064.53

Answers

5 years repayment 11 years maintenance and electricity cost of $24.25

and $0.14, makes the total lifetime cost of the stove b. $2,166.53.

How can the total cost of the stove be calculated?

The cost of the stove = $986

Daily electricity cost = $0.14

Maintenance cost per year = $24.25

Annual Percentage Rate, APR, on the credit card = 9.26%

Number of years the balance was paid off = 5 years using identical monthly payments

Sales tax = 8.22%

Required:

Lifetime total cost of the stove

Solution:

Monthly \ payment, \ M = \mathbf{(P \cdot \left((r)/(12) \right) \cdot \left(1+(r)/(12) \right)^n )/(\left(1+(r)/(12) \right)^n - 1)}

Where;

r = 0.0926

n = 12 × 5 = 60

P = 1.0822 × $986 = $1,067.0492

Which gives;

Monthly \ payment, \ M = \mathbf{(1,067.0492 * \left((0.0926)/(12) \right) \cdot \left(1+(0.0926)/(12) \right)^(60) )/(\left(1+(0.0926)/(12) \right)^(60) - 1)} \approx 22.29

Payment for the purchase ≈ 60 × $22.29 = $1337.4

Amount paid as electricity bill = $0.14 × 365 + 2 × $0.14 = $562.38

The maintenance cost = 11 × $24.25 = $266.75

Which gives;

  • Total stove cost ≈ $1,337.4 + $562.38 + $266.75 = $2,166.53

The selection that gives the total cost is the is the option;

Answer:

2166.53

Step-by-step explanation:

Price x 1.0822 = 1067.0492 <Price with tax

P= PV x i / 1- (1+i)^-n

^ x (identical monthly payments for 5 years aka 12 x 5)

average cost for electricity x (365 x years aka 11)

cost for maintenance x 11
