Jerry has a stamp collection that contains only 3 cent stamps and 5 cent stamps He has 51 stamps altogether and they are worth 2.23 How many of each stamp does Jerry have?

Let ' T ' = the number of 3-cent stamps. Furthermore, let ' F ' = the number of 5-cent stamps. T + F = 51, ===> so F = 51 - T 3T + 5F = 223 3T + 5(51-T) = 223 3T + 255 - 5T = 223 -2T = -32 T = 16 ===> so F = 35


What is the number for white gold?

The stamps only indicate the carat of metal. They do not indicate the color of the metal. So for example an 18ct yellow gold ring would have a stamp of 750 as would an 18ct white gold ring. For 9ct gold the stamp will normally be the number 375 For 14ct gold the stamp will normally be the number 585 For 18ct gold the stamp will normally be the number 750


Who sells stamps?

Stamp Dealer Actually, I sell US postage stamps on eBay. I sell about 20 to 50 a month. That may seem low, but they sell. Before I sell a stamp I have to know exactly what I am selling, therefore there is a process of identification and grading. Then the stamp is posted on eBay. You do not have to be a dealer to sell stamps. Collectors buy, sell and trade stamps all of the time.

Why isn't the price on US stamp?

Since in the last several years the price (of postage as well as goods in general) has risen so fast, the price of a stamp has changed often. This has made it difficult to plan on buying stamps, adding a two- or three-cent stamp to make up the difference when using up stamps bought before the last increase. With the "Forever" stamp, you can buy a supply of them, and you don't have to mess around with additional stamps to make up the difference.
