<h3><u>The function that represents the price P of the car after x years is:</u></h3>

P = 25000(0.935)^x

<em><u>Solution:</u></em>

<em><u>The decreasing function is given as:</u></em>

y = a(1 - r)^t

Where,

y is future value

a is initial value

r is decreasing rate in decimal

t is time period

From given,

a = 25000

r = 6.5 \% = \frac{6.5}{100} = 0.065

number of years = x

future value = P

Therefore,

P = 25000(1 - 0.065)^x\\\\P = 25000(0.935)^x

Thus the function is found

Andrei [34K]

Answer:

  decrease of 64.3%

Step-by-step explanation:

Percentage change can be calculated from ...

  pct change = ((new value)/(original value) -1) × 100%

  = (50/140 -1) × 100%

  = (-9/14)×100% = -64 2/7% ≈ -64.3%

The price of crude fell about 64.3% in that period.
