Patricia wants to order business cards. A printing company determines the cost (C) to the customer using the following function, where b = the number of boxes of cards and n = number of ink colors.
\(C = \$25.60b + \$14.00b(n − 1)\)
If Patricia orders 4 boxes of cards printed in 3 colors, how much will the cards cost?
Substitute 4 for b and 3 for n into the function. Then, solve the equation. \(C= \$25.60(4) + \$14(4)(3 − 1) = \$102.40 + \$112.00 = $214.40\)
