Answer:

399 cars will be sold in 2020

Step-by-step explanation:

Using exponential decay formula:

y = a(1 - r)^{x}

a = intial value at 2012 : 500

r = 2.8 %

= \frac{2.8}{100} = 0.028

x = time interval : 8

y = 500 (1 - 0.028)^{8} \\y = 500 (0.972)^{8}\\y = 500 (0.797)\\ y = 399

Algebra help needed!!
Leni [432]
The population triples ( P × 3 ) every ten minutes...

So if ten minutes is reached there will be 1,200 bacteria.

Edited - missed the question
** The units for time should be in minutes.

P = 400 × 3^(t/10)

at t = 0 ; P = 400
at t = 10 ; P = 1,200

When P = 600
600 = 400 × 3^(t/10)
6/4 = 3^(t/10)
Log(3/2) = Log(3^(t/10))
power rule
Log(3/2) = (t/10) Log(3)
10 × Log(3/2)/Log(3) = t

3.69 minutes the population will be at 600 bacteria
Unites for time are in minutes.
