Answer:
9 tacos and 5 hot dogs.
Explanation:
In this case, Sebastian and his children spent $45.
He bought hot dogs, each worth $4.5 and tacos per $2.5 each and that they bought 14 items.
If we multiply 4.5*5 and then we multiply 2.5*9 we get the following results: 22.5 and 22.5.
We must add them and the final result is 45.
This is how we know that he spent 22.5 dollars on nine tacos and 22.5 dollars on 5 hot dogs.
