1. Find the percent markup.
Markup ($) = percent markup (%) x original cost ($)
A computer store buys a laptop for $635 directly from the manufacturer (Dell). The markup is $570. What is the percent markup on the computer?
The percent markup is: <u> </u><u>90</u><u> </u>%

FORMULA: Percent of Markup = Markup/Cost x 100
- = $570/$635 x 100
- = 0.90 x 100
- = 90%
Matrices always go row x column.
Count the rows: 4
Count the columns: 3
The matrix is a 4 x 3 matrix
