Answer:
18 ft
Step-by-step explanation:
Since the triangle is right angled ; we could use trigonometry ;
Using the angle , 40° ; adjacent side, = 14 feets ; hypotenus = x
Cos θ = Adjacent / hypotenus
Cos 40 = 14 / x
0.7660444 = 14 / x
0.7660444x = 14
x = 14 / 0.7660444
x = 18.27
= 18 ( nearest foot)
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%
