Mailboxes Plus sends packages overnight for $\5$ plus $\0.25$ per ounce. United Packages charges $\2$ plus $\0.35$ per ounce. Mr. Molinari noticed that his package would cost the same to mail using either service. How much does his package weigh?

Write equations for both brands.

$y=$ total cost
$x=$ weight in ounces

Mailboxes Plus: $y=0.25x+5$
United Packages: Write a similar equation.

Set the equations equal to each other to solve for $x$.
