The Brewers spent $28 buying new toys for
their cats and dogs. Dog toys cost $6 each
and cat toys cost $5 each. How many of
each type of toy did the Brewers buy?
DOG TIMES
Zero says: First, take a guess at how many dog
toys they bought: 0
Now check to see if that answer works. Figure
out how much money it would cost to buy that
number of dog toys:
(your (price of
guess) 1 dog toy)
Subtract that amount from the total the
Brewers spent:
(total (price of
spent) dog toys)
Is what's left divisible by the price of one cat
toy? If so, divide to find the number of cat
toys they bought. If not, start again with a
new guess for the dog toys.
