Calculate AC
Round to the nearest tenth.

3,266.53

Step-by-step explanation:

i looked it up :)

34 hours for bob because 100 divided by 3 is 33.333 and you would round up because you would need the extra hour to finish and sell the extra vacuum.

Susan would take 50 hours because 1 every 30 minutes that would be 2 per hour so 100 divided by 2 is 50 so 50 hours.

So it would take 34 hours for someone to earn the $1000 bonus and that person would be Bob.
