6. Javier and his brother Antonio are selling bags of popcorn to raise money for their baseball team to travel to Florida for a tournament.
• Javier is selling his bags of popcorn for $7.50 each and has already raised $120.00.
• Antonio is selling his bags of popcorn for $6.00 each and has already raised $162.00.
Which equation can be used to determine x, the number of bags of popcorn Javier and Antonio must each sell, so that the total amount of money they raise is the same?
120 − 7.50x = 162 − 6x
7.50x − 120 = 6x − 162
120x + 7.50 = 162x + 6
7.50x + 120 = 6x + 162
