Part a: maria rented a coat at $285 for 3 days. if she rents the same coat for 6 days, she has to pay a total rent of $510. write an equation in standard form to represent the total rent (y) that maria has to pay for renting the coat for x days. part b: write the equation obtained in part a using function notation. part c: describe the steps to graph the equation obtained above on the coordinate axes. mention the labels on the axes and the interval

Using $285 for 3 days and $510 for 6 days, we get
285/3 = 95
510/6 = 85
which seem to be different rates per day, but we need to look at it differently.

For 6 days, you pay $510.
For 3 days you pay $285.
The difference between those two rentals is 3 days and $510 - $285 = $225.
The rental amount due to teh daily rate is $225.
$225/3 = $75.

For each day you rent, you must pay $75.
The rest of the payment is a one-time fee for the rental.

3 days due to daily rental fee: 3 * 75 = 225
Problem tells us that for 3 days, it's $285.
$285 - $225 = $60
One-time fee = $60

y = 75x + 60

f(x) = 75x + 60

Hey dear, hoping i'll be

Well is there a picture
