Question 223019: This question is from my beginning algebra textbook and I have tried it two different ways and still can't seem to come up with the right answer.
Here is the problem: In January 2006 U.S. first-class mail rates increased to 39 cents for the first ounce, plus 24 cents for each additional ounce. If Sabrina spent $15.00 for a total of 45 stamps of these two denominations, how many stamps of each denomination did she buy?
I used x for the 39 cent stamps and x-15 for the 24 cent stamps and have tried to work it out like this: x+x-15+45, that didn't work so I tried it this way: x+x-15=$15.00 and that didn't work either. I know the answer is 28 39 cent stamps and 17 24 cent stamps but I like to know how to work them out because I learn better that way. Please help me to work it out the right way.
