The package weighs 30 ounces.
Step-by-step explanation:
Mailbox Plus charges;
Charges per ounce = $0.25
Let,
x be the number of ounces.
M(x)=5+0.25x
United packges charges;
Charges per ounce = $0.35
U(x) = 2+0.35x
Cost will be same when the functions are equal;
M(x) = U(x)
[tex]5+0.25x=2+0.35x\\5-2=0.35x-0.25x\\3=0.10x\\0.10x=3\\[/tex]
Dividing both sides by 0.10
[tex]\frac{0.10x}{0.10}=\frac{3}{0.10}\\x=30[/tex]
The package weighs 30 ounces.
