You are a Business Analyst working for the ABC Ball Bearing company. An hour ago, you sent an order of 74 boxes of your A1 ball bearings to a customer on your delivery truck. You have just found out that your truck is going to go over a bridge that has a weight limit of 11,500 lbs. You need to determine if your truck will safely make it over the bridge. If you determine that the truck cannot make it over the bridge, you will need to call the driver and have him/her turn back. The plant manager has told you that an empty delivery truck with the driver weighs about 8,500 lbs. You have 30 boxes of the A1 ball bearings in your plant. You immediately had them weighed. The weights of the boxes are:

1. 190 lbs
2. 210 lbs
3. 195 lbs
4. 205 lbs
5. 200 lbs
6. 180 lbs
7. 220 lbs
8. 200 lbs
9. 210 lbs
10. 190 lbs
11. 205 lbs
12. 195 lbs
13. 200 lbs
14. 210 lbs
15. 195 lbs
16. 205 lbs
17. 200 lbs
18. 220 lbs
19. 200 lbs
20. 210 lbs
21. 195 lbs
22. 205 lbs
23. 200 lbs
24. 210 lbs
25. 195 lbs
26. 205 lbs
27. 200 lbs
28. 220 lbs
29. 200 lbs
30. 210 lbs

To determine if the truck can cross the bridge, you will first calculate the average weight of a box of ball bearings, then find the total weight of all the boxes in the truck. Add that to the weight of the empty truck. If this is less than or equal to the bridge weight limit, the truck can cross. If it's more, the driver will need to turn back.

Explanation:

The first thing you need to do is to calculate the average weight of a box of A1 ball bearings. You can do this by adding up all of the weights of the 30 boxes you have and then divide by 30. Let's assume that the average weight you find is 'w' lbs. Following this, you'll need to find the total weight of the 74 boxes that are in the truck. This will be 74 multiplied by the average weight 'w'. Let's call this T.

Next, you add the weight of the empty delivery truck, which is 8500 lbs, to the weight of the 74 boxes of ball bearings (T) to find the total weight of the loaded truck. If this total weight is less than or equal to 11,500 lbs, the truck will be able to cross the bridge safely. If it is more than 11,500 lbs, the driver will need to turn back.
