Greeley [361]

X - y + x + y = 180
2x = 180
x = 90
2x - 2y = x + y
x = 3y
y = x/3
y = 90/3
y = 30

x - y = 90 - 30 = 60
x + y = 90 + 30 = 120
2x - 2y = 180 - 60 = 120

Consider the exponential function

evablogger [386]

Given:

The given function $f(x)=19,000 \cdot 0.96 ^x$ which models the value of Mark’s car, where x represents the number of years since he purchased the car.

We need to determine the approximate value of Mark's car after 7 years.

Value of the car:

The value of the car after 7 years can be determined by substituting x = 7 in the function $f(x)=19,000 \cdot 0.96 ^x$ , we get;

$f(7)=19,000 \cdot 0.96 ^7$

$f(7)=19,000 \cdot 0.7514474781$

$f(7)=14277.502$

Rounding off to the nearest dollar, we get;

$f(7)=14278$

Thus, the approximate value of Mark's car after 7 years is $14278.

Hence, Option a is the correct answer.
