The price of mailing a small package is $0.32 for the first ounce and $0.21 for an additional ounce. Simone paid $1.16 to mail her package. How much does it weigh?

Solution:

The price of mailing a small package is $0.32 for the first ounce

$0.21 for an additional ounce

Let "x" be the additional ounces

From given,

Simone paid $1.16 to mail her package

First ounce = $ 0.32

Therefore,

Money paid for additional ounces = 1.16 - 0.32 = $ 0.84

Given that,

$0.21 for an additional ounce

Therefore,

Thus weight of package = first ounce + 4 additional ounces = 5 ounces

Thus the weight of small package is 5 ounces
