Question

The equation p = 1.95t^2 + 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

$496,000
$553,000
$614,000
$678,000

Answer 1

Answer:

$496, 000

Step-by-step explanation:

2021 is 11 years since 2010, hence t = 11

Substitute t = 11 into the equation

p = (1.95 × 11²) + (12.25 × 11) + 125

  = 235.95 + 134.75 + 125

  = 495.7 ( thousands of dollars ), thus the best estimate is

p = $ 496, 000
