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%

Answer:
4376
Step-by-step explanation:
8, −24, 72, -216, 648, -1944, 5832
Multiply the next number by -3
8 x -3 = -24
-24 x -3 = 72
72 x -3 = -216
-216 x -3 = 648
648 x -3 = -1944
-1944 x -3 = 5832
adding all 7 numbers
8 + (−24)+72 + (-216)+648+ (-1944)+5832 = 4376
