on this part: Jennifer to complete this job on her own.

Answer 9

The problem states that carl can paint a room 3 hrs faster so set it up by
Let x = number of hours that Carl takes now we can express jennifer's times
x + 3 is the time that Jennifer takes. The problem further states that working together the can complete the job in 2 hrs.

Use the formula that Hero provided
ie the product over the sum
(x(x+3))/x + x + 3 or
(x^2 + 3x)/x^2-x-6 = 2 Now continue to solve for x + 3 (Jennifers time)
