Answer:
r > 30
Explanation:
Let's look for key words in our problem:
"More Than" means greater than this number. In our problem, this means more than 30 robots can be built.
Using our key words, let's create an inequality.
The greater sign '>' will be used.
r > 30.
This inequality represents more than 30 robots can be built, limiting the options of r being equal to, or less than.
Best luck on your homework!
