Answer:
13.44 or 13 11/25 hours
Step-by-step explanation:
First use this format: number of essays/hours
- they are asking if all three work together, how many hours would it take, so this means addition:
50/7 + 50/14 + 25/6 = 200/x
Second, solve:
- least common multiple: 42
300/42 + 150/42 + 175/6 = 200/x
625/42 = 200/x
- cross-multiply
625x = 8,400
x = 336/25 = 13 11/25 = 13.44 (any one of these answers would work)
Answer: x=20
