Belle eats 4 dog biscuits and 2 rawhide bones every evening. If each rawhide bone is $1, and each dog biscuit is $0.25, then how much does it cost, in dollars, to feed Belle these treats for a week?
Thoughts? Step-by-step reasoning:
User
A week's worth of rawhide bones cost 1 * 2 * 7 = 14 dollars. A week's worth of dog biscuits cost 0.25 * 4 * 7 = 7 dollars,. Thus, in total, it cost 14 + 7 = 21 dollars.
Thus, the answer is 21.
