You would change $20 to pennies, so you would have 2000 pennies. Divide 2000 by 38 to get the answer. In this case it would be 52 stamps with 24 cents left over.
Let the number of 25-cent stamps be ( x ) and the number of 29-cent stamps be ( y ). We have two equations based on the problem: ( x + y = 28 ) (the total number of stamps) and ( 0.25x + 0.29y = 7.60 ) (the total cost of the stamps). Solving these equations simultaneously, we find that Tim bought 16 of the 25-cent stamps and 12 of the 29-cent stamps.
That will depend on the value of the stamps you have. If you have one cent stamps you will need 190 of them. If you have ten cent stamps you only need 19.

If Charlie uses $1.29 in postage to send a package to his sister and only uses 16 cent stamps and 7 cent stamps, he will use 5 16 cent stamps and 7 7 cent stamps.

a dozen
Yes, there are two cent stamps. They have been available almost since the first stamps were issued. For many decades the postage rate in the US was two cents. Today they are mostly used to add to other stamps to make up a new rate.
Its a trick question there are always 12 items in a dozen, it does not matter what they are. so a dozen stamps is 12 no matter what.
