Answer:

8.43 years

Step-by-step explanation:

Given data

Cost price P= $4995

Rate r= 10%

FInal amount A= $2150

The expression for the time/duration is given as

t= ln(A/p)/r

t= ln(2150/4995)/0.1

t= ln(0.430)/0.1

t= 0.843/0.1

t= 8.43

Hence the time it will take is 8.43 years

Nathan just bought a car. He models the value, V, in dollars, of the car after t years as V(t)=21,000(0.861)^t. Based on this mo
Snezhnost [94]

Answer:

Value of the car is decreasing by 13.9% each year.

Step-by-step explanation:

This equation tells us V(t) is the value of the car after a certain time in years, $21,000 is the initial value of the car.  What we need to focus on is on the 0.861 part of this equation.  This means that the price of the car is worth 0.861 or 86.1% of what it was worth the year prior, this means that the price of the car is decreasing over time.  By how much is it decreasing? Well if we consider 1 to mean 100% (since 100 / 100 =1) then we have 100%-86.1%=13.9%.  This means that the value of the car is decreasing 13.9% each year.

Zina [86]

Answer:

$356

Step-by-step explanation:

To solve this problem, use this: (200 * 3.78) - (200 * 2)

(200 * 3.78) - (200 * 2)

<em>200 * 3.78 is the same as 2 * 378, which is 756.</em>

756 - (200 * 2)

<em>200 * 2 is the same as 4 * 100, which is 400.</em>

756 - 400

<em>Subtract 400 from 756 to get 356.</em>

356

If they brought the pizza last week, the school could have saved $356.
