Darla can do a job in eight hours while Lonnie can do the same job in six hours. Both Darla and Lonnie work three hours on the job. How much of the job is left to be finished

Look below ⏬

Step-by-step explanation:

Darla 8h

Lonnie 6h

They both worked 3 hours now

subtract

8-3=5

6-3=3

Darla have 5 hours to finish

and...

Lonnie has 3 hours to finish

all together is 8 hours in all

Step-by-step explanation:

Time/work completed so far

Darla 3/8

Lonnie 3/6 = 1/2

Add together to get completed work so far to determine what's left.

1/2 = 4/8 to create common denominators

3/8 + 4/8 = 7/8 completed so therefore has 1/8 of the job remaining between the two of them.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14
