[Question]: 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?
[Answer]: Muffy weighs 12 - 3 = 9 ounces. Puffy weighs 5 + 9 = 14 ounces. If Brittany weighs both Puffy and Muffy, the scale would read 9 + 14 = 23 ounces.
So the answer is 23.

[Question]: Ray has 95 cents in nickels. If Ray gives 25 cents to Peter, and twice as many cents to Randi as he gave to Peter, how many nickels does Ray have left?
[Answer]: Ray gave 25 * 2 = 50 cents to Randi. Ray has 95 - 25 - 50 = 20 cents in nickels left. Ray has 20 / 5 = 4 nickels.
So the answer is 4.
