Diana and some friends want to go to the movies, if they have to pay $15 to get in the movie theater and then $2 for each bag of popcorn that they buy(p), then how many bags of popcorn did they buy if they spent $45 all together?

Respuesta :

Answer:

15

Step-by-step explanation:

If they started of paying 15 then that's your constant. So what you do is subtract 15 from 45 and see what's left which will be 30. Since each bag of popcorn is $2 you divide the $30 dollars you have left over by 2 and you'll get 15 for the amount of popcorn bags they'll have to buy.
