At an apple orchard, customers use a standard-size box when picking apples. The table shows the total weight of the box of apples and the weight of the apples alone.

Question: Which statement is true?

The equation a= 7.5t models the relationship.

If the total weight of the box is 15 lb, then the weight of the apples is 13.5 lb.

If the total weight of the box is 20 lb, then the weight of the apples is 21.5 lb.

To find any value of a, subtract 2.5 from the corresponding value of t

Table:
Total weight of box (lb), t: 7.5

12.5
Weight of apples (lb) a: 6
