Katy bought a motorcycle for n dollars. Years later, she sold it for 0.6n dollars. Which is another way to describe the change in the price of the motorcycle?

A. 40% decrease
B. 60% decrease
C. 6% increase
D. 60% increase

Here 0.6=60%, so the motorcycle is sold for 60% of the purchase price. So the price was reduced by 40%

A

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
