Answer:
1. Byron: 5c + 12.88. Cassandra: 3c+11.50.
2. (5c + 12.88) - (3c + 11.50).
3. Same as 2, I think. I can’t solve the actual expression because the cost of the yogurt is unknown, however the expression simplified is 2c + 1.38
Step-by-step explanation:
1. c is the cost of one container of yogurt. Writing 5c basically means 5xc and it works because Byron bought 5 containers. Cassandra bought 3, so it works the same way.
2. The cost of the yogurt is unknown, so you can’t just substract the total from the other one. Use parentheses that contain the exact same expression that represents the money spent.
