The monthly salaries of a sample of 100 employees were rounded to the nearest ten dollars. they ranged from a low of $1,040 to a high of $1,720. if we want to condense the data into seven classes, what is the most convenient class interval?

1720 - 1040 = 680
680/7 = 97.1

I would put them in intervals of 100

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
