• No mare than 50 seeds will sprout.

• Between 50 and 100 seeds will sprout

• at least 100 but no more than 120 seeds will sprout

• All 120 seeds will sprout.

The table shows the number of bottles of different kinds of juice sold at a cafeteria on Monday.

If the cafeteria has 80 customers on Tuesday, which prediction or Tuesday is NOT supported by the data in the table?

• The number of bottles of cranberry juice sold will be 6 more than the number o bottles of pineapple juice sold.

• The number of bottles of apple juice sold will be 6 times the number of bottles of cranberry juice sold.

• There will be a total of 50 bottles of orange and cranberry juice sold.

• The difference between the number of bottles of app le juice sold and the number o bottles of pineapple juice sold will be 14.
