Answer: Yes, the amount can buy either of them a second salad or a drink.
Step-by-step explanation:
Since a salad cost $2.49 and a bottle of drink cost $0.99, therefore for both of them the total amount they need to spend is (2×$2.49)+(2×$0.99)
= $4.98+$1.98
= $6.96
This is the amount for both of them to get a first salad and a drink.
Since they both have $8.00 with them, their balance will be $8.00-$6.96 which is $1.04
The balance can buy one of them second drink then that is $0.99. So yes, the amount can buy either of them a second salad or a drink.
