Final answer:
The system of inequalities is 6x + 2y ≤ 30 and x + y ≤ 5.
Step-by-step explanation:
To write the system of inequalities for this scenario, we need to define variables for the number of tubs of popcorn and the number of candy bars.
Let x represent the number of tubs of popcorn and y represent the number of candy bars. The constraints are as follows:
- The total cost of snacks should be less than or equal to $30, so the inequality is 6x + 2y ≤ 30.
- The family wants no more than 5 snacks, so the total number of snacks should be less than or equal to 5, so the inequality is x + y ≤ 5.
Therefore, the system of inequalities is:
6x + 2y ≤ 30
x + y ≤ 5
