Answer:
lifetime cost of the Megans TV is $347 .66 .
Step-by-step explanation:
As given
Megan’s TV had a base price of $189 and the sales tax was 6.88%.
6.88 % is written in the decimal form.
= 0.0688
Sales tax price = 0.0688 × Base price
= 0.0688 × 189
= $ 13 (Approx)
As given
Over the next four years, the TV consumed an average of $0.06 of electricity every day.
As 1 year contains 365 days and a leap year contains 366 days .
Thus
Electricity consumed in four years = Average electricity × (3× Number of days in one years + Number of days in a leap year )
= 0.06 × ( 3 × 365 + 366)
= 0.06 × (1095 + 366)
= 0.06 × 1461
= 87.66
As given
It also needed repairs twice, costing $29 each time.
Repair cost = 2 × Cost of repair
= 2 × 29
= $58
Thus
Lifetime cost of the Megans TV = Base cost + Sales price cost + Electricity consumed in four years + Repair cost .
Putting all the values in the above
Lifetime cost of the Megans TV = $189 + $13 + $87.66 + $ 58
= $ 347.66
Therefore the lifetime cost of the Megans TV is $347 .66 .
Given:
Amount = 8700
Time = 3 years
Rate of interest = 24% per annum
To find:
The principal values.
Solution:
Formula for amount:
Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting , we get
Divide both sides by 1.906624.
Therefore, the principal value is about 4563.04.
Answer:
, where, n = 0, 1, 2, 3, 4, .........
Step-by-step explanation:
Given the arithmetic sequence in recursive formula.
f(0) = 30 and f(n + 1) = f(n) + 7 ......... (1)
Therefore, putting n = 0 in equation (1) we get f(1) = f(0) + 7 = 30 + 7 = 37 {Since, f(0) is given to be 30}
Again, putting n = 1 in equation (1) we get f(2) = f(1) + 7 = 37 + 7 = 44
And, putting n = 2 in equation (1) we get f(3) = f(2) + 7 = 44 + 7 = 51
and so on.
Therefore, the arithmetic sequence is 30, 37, 44, 51, .......
Therefore, the linear equation of this sequence is given by , where, n = 0, 1, 2, 3, 4, .........
