We know that

• The new charge was $0.50 to mail a letter weighing up to 1 ounce, and $0.21 for each additional ounce.

Based on the given information, the expression is

$y=0.50+0.21x$

Where <em>x</em> represents additional ounces, and <em>y</em> represents a cost.

<h2>Hence, the function is</h2> $f(x)=0.21x+0.50$
