The Jones family and the Smith family both went out for a night at the movies. The Jones family bought 5 drinks and 2 bags of popcorn for a total of $18.75. The Smith family bought 4 drinks and 6 bags of popcorn for a total of $31.50.

How much does each bag of popcorn cost?

Respuesta :

It's simple. You have to subtract FIRST 18.75-5=13.75 for the Jones Family. Then you divide 13.75 by 2 bags of popcorn which equals $6.87 for the Jones Family.

For Smith Family, subtract 31.50-4=27.50. Then you divide 27.50 by 6 bags of popcorn which equals $4.58
