How many ounces does a First-Class price mailing cost for a 2-ounce letter?

The price of a First-Class mailing for a 2-ounce letter is $0.68 based on the current USPS rates. The pricing for First-Class Mail is structured in a way that the first ounce has a base rate, and each additional ounce increases the cost. For letters, the price increases at certain weight intervals. The first ounce typically starts at a specific price, and for each additional ounce, a predetermined increment is added to the cost. In this instance, the cost reflects both the additional weight and the established pricing model set by USPS.

The other options reflect costs that do not align with the current pricing structure for First-Class letters. Understanding these increments and the overall pricing framework will help you determine costs for various weights of mail efficiently.
