The equation p = 1.95t² + 12.25t + 125 approximates the average sale price p of a house (in thousands of dollars) for years t since 2010. what is the best estimate for the price of the house in year 2021?

Resolving   p = 1.95t² + 12.25t + 125

year=2010   for t=0

year=2021   for t=(2021-2010)=11 

We have that

p = 1.95*(11) ^² + 12.25*(11) + 125

p =495.70 thousands of dollars

p =495700  dollars 

$495,700

Step-by-step explanation:

Given: The equation approximates the average sale price p of a house (in thousands of dollars) for years t since 2010.

In 2021,  

To find the best estimate for the price of the house in year 2021, we need to substitute t=11 in the given equation we get,

Hence, the best estimate for the price of the house in year 2021 is $495,700.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
