Brittany has 3 gerbils: Puffy, Muffy, and Scruffy. Puffy weighs 5 ounces more than Muffy. Muffy weighs 3 ounces less than Scruffy.  If Scruffy weighs 12 ounces, how much would the scale indicate, in ounces, if Brittany put Puffy and Muffy on the scale?
How much does Muffy weigh? ** Muffy weighs 12 - 3 = <<12-3=9>>9 ounces
How much does Puffy weigh? ** Puffy weighs 5 + 9 = <<5+9=14>>14 ounces.
How much would the scale read if Brittany weighed both Muffy and Puffy? ** If Brittany weighs both Puffy and Muffy, the scale would read 9 + 14 = <<9+14=23>>23 ounces
