Answer:
The value after 0 years = $ 800
The value after 1 year = $600
The value after 2 years = $450
The value after 3 years = $337.5
The value after n years = computer cost at (n-1) year -
Step-by-step explanation:
- he cost of computer = $ 800
- It losed 1/4th of value every year.
- The value of computer after 0 years = cost of computer = $ 800
- The value after 1 year = 800 - ( ) = $600
- The value after 2 years = 600 - ( ) = $450
- The value after 3 years = 450 - ( ) = $337.5
- The value after n years = computer cost at (n-1) year -
Rewrite the fractions to have a common denominator to find the difference:
2/3 = 4/6
Difference = 4/6-5/6 = -1/6
Sequence formula = an = a1 + d(n-1)
A1 is the first term 5/6
And d = -1/6
Sequence = 5/6 -1/6(n-1)
Simplify to get an =(-n +6)/6
Hi! the first one is -2+6 i & the second one is parallelogram!
The 2 correct choices are 'a', 'b', and 'c'.
