Answer:
168 bedrooms
Explanation:
You want the number of bedrooms Greg and his partner can paint in 24 hours if they can individually paint 4 and 3 bedrooms per hour, respectively.
Work
The total work is the product of (work per time) and (time).
total work = Greg's work + Partner's work
total work = (4 bdrm/h)(24 h) +(3 bdrm/h)(24 h)
total work = 96 bdrm + 72 bdrm = 168 bdrm
Greg and his partner can paint 168 bedrooms in 24 hours.

Additional comment
This is a little different than the usual "working together" problem. Often the individual rates are given as "time per work", 4 hours per bedroom, for example.
If the work rates were 4 hours and 3 hours per bedroom, respectively, then in 24 hours, they could paint 6 + 8 = 14 bedrooms.
