Answer:
It should be $50.00.
Step-by-step explanation:
It shows that every 2 mins. adds 20 cents to the bill. I wrote out the numbers and did this:
6 30.60
8 30.80
10 40.00
12 40.20
14 40.40
16 40.60
18 40.80
20 50.00
The answer is certainly c because i did that and got it right
560,000+313 = 560,313
560,313-100,000= 460,313
answer is 460,313
Total sales = $3600
Commission earned on $3600 = $576
Commission rate can be calculated as = 
= 16%
Hence, commission rate is 16%
You would do 11 times 8 because you need all the legs of the spiders.
