Answer 1

To determine the approximate interval of weight for the $10 shipping rate based on the provided rates from Shipping Brothers Incorporated, we can analyze the given information:

1. Less than 30 lb: $5 shipping
2. 30 lb to less than 50 lb: $10 shipping
3. 50 lb to less than 75 lb: $15 shipping
4. 75 lb or heavier: $20 shipping

From the information:

• The $10 shipping rate applies to packages that weigh 30 pounds to less than 50 pounds.

Therefore, the approximate interval for the $10 shipping rate is:

\[ \text{Weight interval} = [30 \text{ lbs}, 50 \text{ lbs}) \]

This means that any package weighing 30 lbs up to but not including 50 lbs will incur a shipping fee of $10.
