Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Problem:
C(x) = 0.06x + 8.50
Substitute x for 20:
C(20) = 0.06(20) + 8.50
Multiply 0.06 and 20:
C(20) = 1.2 + 8.50
Add 1.2 and 8.50:
C(20) = $9.70
The total cost for an order of 20 copies is $9.70
