Answer:
$98.15
Step-by-step explanation:
2005 is 15 years after 1990. Using the formula we find ...
c(15) = 63·1.03^15 ≈ 63·1.55797
c(15) ≈ 98.152
An ounce of the chemical costs about $98.15 in 2005.
The amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad is $ 390.24.
Given that:-
Price of the laptop after 1 year = $ 400.
Inflation rate = 2.5 %
We have to find the amount he had to pay if he have to purchase a laptop today that is the same value as the one he saw in the ad.
Let the price he had to pay be x.
Hence, we can write,
x + (x*(2.5)*1)/100 = 400
x(1 + 1/40) = 400
x(41/40) = 400
x = 400*40/41 = $ 16000/41 = $ 390.24.
