Step-by-step explanation:
Each ounce of fruit will supply
- 1 unit of protein,
- 2 units of carbohydrates,
- 1 unit of fat.
Each ounce of nuts will supply
- 1 unit of protein,
- 1 unit of carbohydrates,
- 1 unit of fat.
Let x equal the ounces of fruit and y equal the ounces of nuts to be used in each package.
Then x ounces of fruit will supply
- x units of protein,
- 2x units of carbohydrates,
- x units of fat
and y ounces of nuts will supply
- y units of protein,
- y units of carbohydrates,
- y units of fat.
Every package must provide
- at least 7 units of protein, then x+y≥7,
- at least 11 units of carbohydrates, then 2x+y≥11,
- and no more than 10 units of fat, then x+y≤10.

Answer:
Each point does NOT ALWAYS give the same amount of tickets.
11 point would most likely give 90 tickets.
Step-by-step explanation:
2 points give 18 tickets = 9 tickets per point
3 points give 27 tickets = 9 tickets per point
9 points give 72 tickets = 8 tickets per point
You can add the 2 point value with the 9 point values to find out many point it takes to get to 90 tickets.
18(2 tickets) + 72(9 tickets) = 90(11 tickets)
