Step-by-step explanation:

Use formula to find the slope/gradient

$\frac{y2 - y1}{x2 - x1}$

(-5, -1) = (x1, y1)

(5, 11) = (x2, y2)

So,

$= \frac{11 - ( - 1)}{5 - ( - 5)} \\ = \frac{12}{10 } \\ = \frac{6}{5}$

The average price (in dollars) to rent a studio in a certain city can be approximated by the equation p - 24.1t+575 where t is

krok68 [10]

Answer:

69 years after 2005 which is in 2074 year the average price of a studio in this city will reach $1081.10.

Step-by-step explanation:

Given:

Average Price to rent a studio is denoted by 'p'.

It is been approximated by equation:

$p-24.1t+575$

where t ⇒ number of years since 2005

Now given:

Average Price to rent a studio p = $1081.10

Substituting the value of p in above equation we get;

$1081.10-24.1t+575$

Solving the new equation to find the value of t we get;

$1656.1=24.1t$

Dividing both side by 24.1 we get;

$\frac{1651.1}{24.1} =\frac{24.1t}{24.1} \\\\t= 68.71 \approx 69 years$

Hence 69 years after 2005 which is in 2074 year the average price of a studio in this city will reach $1081.10.
