The appropriate interval for the $10 shipping rate, which applies to packages that weigh from 30 pounds to less than 50 pounds, is:
**30≤x<50**
30 less-than-or-equal-to x less than 50.
This means that if a package weighs 30 pounds or more but less than 50 pounds, the shipping charge will be $10.
**30≤x<50**
30 less-than-or-equal-to x less than 50.
This means that if a package weighs 30 pounds or more but less than 50 pounds, the shipping charge will be $10.
