Sebastian and his children went into a restaurant and he bought $45 worth'of hotdogs and tacos. Each hotdog costs $4.50 and each taco costs $2.50. He bought a total of 14 hotdogs and tacos altogether. Determine the number of hotdogs and the number of tacos that Sebastian bought.

9 tacos and 5 hot dogs.

Step-by-step 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.
