The shipping rate of $4 applies to customers spending between $100 and under $140. Therefore, the correct interval is:
100 ≤ s < 140
This means \( s \) (the amount spent) is at least $100 and less than $140.
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? (1 point) Responses 100<s≤140 100 less than s less than or equal to 140 50≤s<100 50 less than or equal to s less than 100 100≤s<140 100 less than or equal to s less than 140 100<s<140
