Question

To mail a package, UPS charges a $7 flat fee and $2 per pound. FedEx charges

Answer 1

Answer:

The package where they charge the same must cost $2

Step-by-step explanation:

Given

UPS

$Flat = \ 7$

$Additional = \ 2/lb$

FedEx

$Flat = \ 5$

$Additional = \ 3/lb$

Required

What pound do both charges are the same

Represent the charges with x;

For UPS, it can be written as:

$Charges = 7 +2x$

For FedEx:

It is:

$Charges = 5 + 3x$

Equate these charges together

$5 + 3x = 7 + 2x$

Collect Like Terms

$3x - 2x = 7 - 5$

$x = 2$

Hence, the package where they charge the same must cost $2
