The cost for shipping by the Boston Mailing Company is based on the amount that a customer spends. For customers spending under $50, the shipping rate is $10; for $50 to under $100, the shipping rate is $7; for $100 to under $140, the shipping rate is $4; for $140 and over the shipping rate is $2. What domain interval will have a shipping rate of $4?

Question

(1 point)
• 50 ≤ s < 100
• 100 < s ≤ 140
• 100 < s < 140
• 100 ≤ s < 140

Answer 1

To find the domain interval that will have a shipping rate of $4, we look at the conditions given for the shipping costs.

The shipping rate of $4 applies to customers spending between $100 and $140. Therefore, the correct interval is:

100 ≤ s < 140

So, the answer is: • 100 ≤ s < 140
