Answer:
16.065
Step-by-step explanation:
First you have to find 10 percent of 17.85 by dividing 17.85 by 10
10 / 17.85 = 1.785
then you subtract 1.785 by 17.85 to get the original price
(cos(3°) / 5) = 0.201078184 radians
Second option is the correct answer
You can use scale to solve. 5185/8.5=610
4845/610= about 8 hours.
