It helps to think of a simpler problem. Let's say mpg is 20 and 10% higher on a smooth road.
How many miles will you get with one gallon on a regular road?
How many more miles will you get on a smooth road? 10% more, right? How much is that?
OK - so you've now solved a simpler problem. Use the exact some process to solve your, more complicated, problem.
Use SOHCAHTOA
sin(51)=y/12
sin(51) (12)=y
y=<span>8.04275011012</span>
The following effects that can effect a regular employee's pay is from their effort and time.
