Answer
its called x
Step-by-step explanation:
For this, we will be using dimensional analysis as such:

In short, 24,900 miles is 40,072,665.6 (40,072,666 if rounded to the whole meter) meters.
29.99x-8.75x=17884
21.24x=17884
X=841 sunglasses
It actually comes out to be more than 841, but since you can’t make .9 sunglasses then you round to the lower whole number.
