If the rate of inflation is 3.4%per year, the future price pt(in dollars) of a certain item can be modeled by the following expo

Doss [256]

Answer:

The current price is $3000 and price after 9 years from today is $4054.

Step-by-step explanation:

The future price pt(in dollars) of a certain item can be modeled by the following exponential function

$p(t)=3000(1.034)^t$

where, t is the number of years from today.

Substitute t=0 to find the current price.

$p(0)=3000(1.034)^0=3000$

Therefore the current price is $3000.

Substitute t=9 to find the price after 9 years from today.

$p(9)=3000(1.034)^9$

$p(9)=3000(1.35109177087)$

$p(9)=4053.27531261$

$p(9)\approx 4054$

Therefore the price after 9 years from today is $4054.

Daniel [21]

The ratio birds : animals = 13 : 2
so for every 1 animal, 6.5 birds were born

last month: animals = birds - 44
birds - animals = 44
use trial and improvement to find:
if there were 52 birds, there must be 8 animals
CHECK: 52 - 8 = 44
