To send a letter to Country Q, the postal service charges: $0.79 for the first ounce and $0.55 for each additional ounce. How much would it cost to send a letter that weighs 8 ounces?

$4.64

Step-by-step explanation:

The first ounce is charged at $0.79 and then every additional ounce is $0.55.

There are 8 ounces to send.

The cost will therefore be:

= Cost of first ounce + Cost of 7 additional ounces

= 0.79 + (0.55 * 7)

= 0.79 + 3.85

= $4.64

ou would have 12 of each
