Question

A photographer charges a sitting fee of $69.95 for one person. Each additional person in the picture is $30. What is the total sitting fee charge for a group of 10 people to be photographed?

Answer 1

Let

x -----> number of people

y ----> total charge

we have

y=30x+69.95

so

For x=10 people

substitute

y=30(10)+69.95

y=$369.95
