How many stamps?
you have 3 times as many 14 cent stamps as you do 25
cent stamps Altogether you have 8 stamps. How many 25 cent letter
can you mail?
eric glomstad was the first to try and solve this
The stamp question is a simple one. the equation is
as follows x=the number of 14 cent stamps, y=the number of 25 cent
stamps. x plus y =8 and since their are 3 times as many 14 cent
stamps as 25 cent stamps, the second equation is 3y=x Using
substitution, y+3y= 8, or y=2. Therefore, ther are 2 25cent stamps
and 6 14 cent stamps. Now, two 25 cent letters can be sent with the
two 25 cent stamps, but only two more can be sent with the 6 14 cent
stamps since each of these letters must have three 14 cent stamps
apiece. The final answer? FOUR letters may be sent!
Paul then argued Erics answer with this one:
You can mail 2 twenty-five cent letters. 2x3=6,
Jen-nay out did them both with this:
I don't think you can mail any 25 cent letter since the current
postage for a letter is 37 cents.
Lauren: So what have we learned? well we haven't figured out how
many stamps you can send however, it doesn't really matter since
postage is 37 cents!
