Question 82893
The way to work this problem is to start at the end of the problem statement and work your 
way back to the front.
.
At the end of the problem you are told that Bonnie found 8 stores.
.
The next statement back tells you that Salvatore found 4 more stores than Bonnie. Since
Bonnie found 8 stores, Salvatore found 8 + 4 = 12 stores.
.
Then you are told that Gus found 4 stores less than Salvatore. So Gus found 12 - 4 or 8 stores,
the same number as Bonnie.
.
Finally you are told that Neil found twice as many stores as Gus. Since Gus found 8 stores,
that means that Neil found 2 times 8 or 16 stores.
.
This means that the total number of stores the four of them found was:
.
8 + 12 + 8 + 16
.
and since this sums to 44, the group did not qualify for the bonus because they did not
locate 50 new stores.
.
Hope this helps you to understand the problem.
