Subjects in Portrait

Base Price

1

$100

2

$130

3

$150

$160

5 or more

$165

Fancy background add-on costs an extra 10 percent more than the base price.

Portrait sitting on Saturday costs an extra 30 percent, on Sunday costs 20 percent more than the base price.

Use the if statement, but no loops.
