write it as an equation.
The appropriate interval for the $10 shipping rate can be written as the inequality:
\[ 30 \leq w < 50 \]
where \( w \) represents the weight of the package in pounds. This notation indicates that the weight \( w \) is greater than or equal to 30 pounds but less than 50 pounds.
