**The cost of mailing a DVD in an envelope by express mail is equal to the cost of mailing a DVD in a box by priority mail. What is the weight of the DVD with its packing material? Round your answer to the nearest hundredth.**

| | Packing Material Cost | Priority Mail Cost per lb | Express Mail Cost per lb |
|----------------|------------------------|---------------------------|--------------------------|
| Box | $2.25 | $2.50 | $8.50 |
| Envelope | $1.10 | $2.50 | $8.50 |

eight of the DVD with packing material is 0.19 lb. 1.10+8.5x=2.25+2.5x Move variables to one side. The easier one would be to move 2.5x. So you subtract 2.5x to both sides. 1.10+6x=2.25 Do the same for the values without the x. The easier one would be to subtract 1.10 from both sides. 6x=1.15 Then divide by 6 1.15/6=0.19

The weight of the DVD with its packing material is 0.38 pounds. This was calculated by setting the cost of mailing in an envelope equal to the cost of mailing in a box and solving for the weight. The final equation showed that the weight was 0.375 pounds, rounded to 0.38 pounds.
