Question

Jeff has ten packages that he wants to mail. Nine identical packages that weigh 2 7/8 pounds each. A tenth package weighs two times as much of one the nine packages. How many ponds do all packages weigh?

Answer 1

31 5/8 pounds

Explanation:

The total weight is ...

9(2 7/8 lb) + 2(2 7/8 lb) = (2 7/8 lb)(9 +1) = (23/8 lb)(11) = 253/8 lb

= 31 5/8 lb

The total of package weights is 31 5/8 pounds.
