Answer:

1. No

2. 1,050 bushels of corn

Step-by-step explanation:

1. A number is proportional if it has a constant ratio to another quantity.

8/12 and 10/25 do not.

2. An acre will produce \frac{750}{10} bushels of corn.

750 divided by 10 is 75. <u>This is 75 bushels per acre.</u>

Then you would multiply 75 and 14.

This equals 1,050 bushels of corn.
