Question

Phil has 11 stamps of denominations $0.37 and $0.23. If the total value of the stamps is $3.23 how many $0.23 stamps does Phil have?

Answer 1

i would use a system of equations. x represents # of 23 cent stamps, and y 37 cent.
You also know the total is 11.

So:
x+y=11
.23*(x)+.37*(y)=3.23


Solve this system of equations.

Answer 2

Is this answer correct?
x=14.0435-1.6087y

Answer 3

sry, i dont think so. I got 6 23 cent stamps, and 5 37 cent stamps

Answer 4

>x+y=11
>>x=11-y

Replace all x in the other equation with (11-y):
>.23*(x)+.37*(y)=3.23
>>.23*(11-y)+.37*(y)=3.23

and so on..

Answer 5

So is it 5?
