Answer:

24 hours

Step-by-step explanation:

Kristen = 8 hours

Kristen and Courtney = 6 hours

Courtney = x hours

in six hours kirsten can do 6/8 of the job

6/8 = 3/4

So kirsten is going to be doing 3/4 of the job

Courtney is only going to do 1/4 of the job

Number of hours it takes Courtney to do the job

6/x = 1/4

Cross product

6 * 4 = x * 1

24 = x

x = 24 hours

It will take Courtney 24 hours to type a 50-page paper on her own
