To find out how many pounds of apples Mason has left, we need to subtract the total weight of the apples he sold from the initial weight of 1,015 pounds.
First, let's calculate the weight of the apples Mason sold:
- 1 bushel is approximately equal to 48 pounds.
- 1 box is approximately equal to 20 pounds.
- 1 bag is approximately equal to 10 pounds.
So, the weight of 9 bushels is 9 x 48 = 432 pounds.
The weight of 25 boxes is 25 x 20 = 500 pounds.
The weight of 40 bags is 40 x 10 = 400 pounds.
Now, let's add the weights of the sold apples:
432 + 500 + 400 = 1,332 pounds
Finally, we can find the remaining weight by subtracting the weight of the sold apples from the initial weight:
1,015 - 1,332 = -317 pounds
