Travis needs to mail 12 letters and 25 postcards. A letter needs a 79-cent stamp and a postcard needs a 30-cent stamp. How much money will Travis spend for postage?

$16.98

Step-by-step explanation:

First you have to multiply the amount of letters and postcards by the amount each stamps costs:

12x0.79=9.48

25x0.30=7.50

Then add those values together to get the total:

9.48+7.50=16.98

$16.98 is your answer
