Answer:
56 hotdogs, 168 sodas.
Explanation:
# of sodas sold = s
# of hotdogs sold = h
224 sodas and hotdogs = s + h
3h = s
224 = h + s
Plug in one equation into the other one, like 3h = s into h + s
h + s = 224 and s = 3h so...
h + (3h) = 224
4h = 224
h = 224/4 = 56
56 hotdogs were sold
And since s = 3h...
The number of sodas sold is 3 times 56 = 168 sodas.
56 hotdogs, 168 sodas.
