1)a jogging trail is 2 miles. a distance marker is placed every 1/5 mile. how many distance markers are there show how you found your answer

To solve this, I will find out how many one-fifths there are in two miles. 
The equation 2/1 ÷ 1/5 can show me the answer to this question.
I will have to flip the second fraction to make this into a multiplying fraction.
2/1 × 5/1 = ?
Now I have to multiply across:
2 × 5 = 10 and 1 × 1 = 1
The answer is 10/1, or in simple terms, 10.
There are 10 distant markers in the two-mile trail.

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
