Question

Kim is a photographer who specializes in family portraits. She charges a $75 sitting fee plus $18 for each print ordered. Which equation represents the amount, a Kim would charge for a photo session when p prints are ordered
A.) p=75a+18
B.) a=18p+75
C.) a=75p+18
D.) p=18a+75

Answer 1

$75 is a one time fee or the constant.
$18 is a fee for each time a print is ordered.


let me do an example

I charge a $5 fee to come in to my store. And I charge $1 for each cookie. Write an equation.

$5 is the constant or the y-intercept
$1 is going to be the slope because each time I order a cookie (which is x) I will increase by 1

y = mx + b, where m is the slope and b is the y-intercept

the equation would be

y = 1x + 5

now do it for your question how I did it for the example :)

Answer 2

So just to be clear is it p=18a+75??

Answer 3

you have the variables switched

you get charged 18 for each print, or p

a is the total cose at the end :)
