a post office always charges a flat one time fee for any order. one time, michael sent 35 letters and paid 26 dollars. the next time, he sent 18 letters and paid $14.10. how much does the post office charge to send one letter? what is the flat fee?

Respuesta :

Answer:

$0.70 per letter, $1.50 flat fee

Step-by-step explanation:

x+18y=14.1 -> x=-18y+14.1

x+35y=26

|

\/

(-18y+14.1)+35y=26 -> 17y=11.9 -> y=0.7

|

\/

x+35(0.7)=26 -> x+24.5=26 -> x=1.5

|

\/

y=0.7

x=1.5

Hope this helps. :)
