If you would like to find the percent markup, you can calculate this using the following steps:
x% of $20 is $29
x% * 20 = 29
x/100 * 20 = 29
x = 29 * 100 / 20
x = 145%
145% - 100% = 45%
The correct result would be 45%.
The answer is C. 51/4. Hope I helped!
Parametize C of the line integral as

from 0<=t<1 then

which means by substituting x with e^t and y with and dx with e^t dt we get

by adding exponents

Answer: x ≤ 5
