Question 865688: Hi, I am having a hard time knowing how to set up and solve this word problem:
Working together, Dani and Cheri can reply to a day's worth of costumer-service emails in 4hr. Working alone, Dani takes 6 hr longer than Cheri. How long would it take Cheri alone to reply to the e-mails?
Thanks!

1/d+1/c=1/4,
d=c+6
c = 6, d = 12
1/6+1/12=1/4
check
2/12+1/12=3/12
ok
