The value of a record player in 2015 was 295.00. The product decreased in value at an expected rate of 17.50 per year. A)
Write a linear equation the gives its value in terms of the year.
B) When will the record player have no value?
Thank you!
v = 295 - 17.50x
find x-intercept
V = 295 - 17.50 (Year-2015)
V = 295 + 35262.50 - 17.50 * Year
V = 35557.50 - 17.50 * Year
0 = 35557.50 - 17.50 * Year
Year = 35557.50 / 17.50
Year = 2031.857143 for V = 0
=================
check
2031.857 - 2015 = 16.857 years
17.50 * 16.857 = 294.99
ah, missed by a penny :)
