Question

A travel trailer is bought at the price of $35,000. The price decreases at the rate of .25 every year (t). The exponential expression is 35,000(.75)^t. Find the price of the trailer at 5 years.

Answer 1

Answer:

$ 8300 (Approximately)

Step-by-step explanation:

Given:

Initial price of the trailer is, $P_0=\ 35000$

Rate of decrease per year is, $r=0.25$

The time in years is, $t=5$

The exponential expression for the decrease in price after 't' years is given as:

$P=P_0(1-r)^t$

Plug in all the given values and solve for 'P'. This gives,

$P=35000(1-0.25)^5\\P=35000(0.75)^5\\P=35000(0.2373)\\P=\ 8305.5\approx \ 8300$

Rounding it to the nearest whole number, the price of the travel trailer after 5 years is $ 8,300.
