Answer:
$ 8300 (Approximately)
Step-by-step explanation:
Given:
Initial price of the trailer is,
Rate of decrease per year is,
The time in years is,
The exponential expression for the decrease in price after 't' years is given as:
Plug in all the given values and solve for 'P'. This gives,
Rounding it to the nearest whole number, the price of the travel trailer after 5 years is $ 8,300.
Kriste respone is wrong
<em><u>Solution:</u></em>
Given that,
Kristen was asked to write each of the numbers in the expression 80,000 x 25 using exponents
Her response was (8 x 10 to the power of 3) x 5 to the power of 2
No, the response of Kristen is wrong
Let us first understand about exponents
An exponent refers to the number of times a number is multiplied by itself
Given expression is:
Here, 80000 has 4 zeros
Therefore, it can be raised as 10 power 4
<em><u>Thus the expression becomes:</u></em>
Also, 25 can be written as 5 power 2
Thus given expression is written as (8 x 10 to the power 4) x 5 power to the power 2
Thus Kristen respone is wrong, because he has raised 10 to power 3
