Would someone please check my answers to this problem:
The license fee for a car varies directly with the value of the car. The fee for a car that is valued at $19,500 is $292.50.
What is the constant of proportionality? My answer is: .105 cents per every one dollar of car value.
Write the equation that shows the license fee as a function on the value of the car. My answer is: License fee=Y and car value = x. y=.105 x
If you were to draw the graph of this function, what would be the slope of the line? My answer is: m=.105
If you were to draw the graph of this function, what would be the y-intercept. My answer is: The y intercept would be 0.
At this rate, what is the license fee for a car that is valued at $25,400. My answer is $381.00
set up proportion
19500/292.50 = 1/x
solve for x
x= 0.015
Now do your function
Looks good, but you probably meant to type 0.015 instead of .105
Did I answer all the parts correctly?
