- Combine the like terms
- Write in descending order
A). 4 (8m-7n) +6 (3n-4m)
32m - 28n + 18n -24m
8m -10n
B). 9 (r-s) + 5 (2r-2s)
9r-9s+10r-10s
19r-19s
C). 12 (1-3g)+8 (g+f)
12 - 36g + 8g + 8f
12 - 28g + 8f

If Matthew wants to complete packages at an average rate of at least 39 packages per hour.
And they worked 4 hrs only due to picnic, yesterday, it means they have to make packages.
But they made only 112 packages means they are short of packages.
Suppose they are working today t hrs, and his department will complete 43 packages per hour today.
It means they are going to make 43 t packages today.

Cross multiplying
Adding 44 in both sides
Subtracting 39 t in both sides
Dividing 4 in both sides
t = 11 hrs
Hence they have to woth 11 hrs today : Answer
