T-shirt with Printing (Product Price Formula example 2)

Let's say you provide t-shirt printing services. T-shirt base price is $5.00 for QTY < 10 and $4.00 for QTY >= 10. Printing cost per t-shirt is $1.00 for QTY < 10 and $0.80 for QTY >= 10. You also charge a onetime setup fee of $6.00 not depending on the QTY. I.e.:

if ({qty} < 10) Row Total = 5 * {qty} + 1 * {qty} + 6
if ({qty} >= 10) Row Total = 4 * {qty} + 0.8 * {qty} + 6
