In the question, it is already given that the total number of runners in the race is 60 and out of them 1/3 dropped out in the first half. In the second half 1/4 of the remaining runners dropped out.
Now
Total number of runners in the race = 60
Number of runners that dropped out in the first half = 1/3 * 60
= 20
Number of runners remaining = 60 - 20
= 40
Number of runners dropping out in the second half = 40 * 1/4
= 10
Then the number of runners that finished the race = 40 - 10
= 30
Then 30 runners completed the race.
Answer:
G = $612.50 when H = 46hours
Step-by-step explanation:
Given:
G = 18.75(H-40) + 500
Where,
G =Gross pay in dollars
H = Number of hours worked
If her gross pay one week was $612.50, what was the
total number of hours she worked that week?
G = $612.50 when H = ?
G = 18.75(H-40) + 500
612.50 = 18.75H - 750 + 500
612.50 = 18.75H - 250
Add 250 to both sides
612.50 + 250 = 18.75H
862.5 = 18.75H
Divide both sides by 18.75
862.5 / 18.75 = 18.75H / 18.75
46 = H
H = 46
If her gross pay one week was $612.50, her total hours worked = 46hours
