Question 1154613: One group of customers bought 7 deluxe hamburgers, 5 orders of large fries, and 6 large colas for $24.30. A second group ordered 9 deluxe hamburgers, 5 large fries, and 7 large colas and paid $29.30. Is there sufficient information to determine the price of each food item? Assume that the hamburgers cost between $1.50 and $2.50, the fries between $0.50 and $1.50, and the colas between $0.60 and $0.90.

No, there is not enough information.
The difference between the two purchases is 2 burgers and 1 soda for an additional $5.
It is possible to choose different costs of burgers and sodas in the specified ranges that satisfy that and yield prices for the fries that are also in the required range. E.g.,...
Choose $0.60 for the cost of a soda --> cost of a burger is $2.20 --> cost of a fries is $1.06
or...
Choose $0.90 for the cost of a soda --> cost of a burger is $2.05 --> cost of a fries is $0.91
