I'm in financial algebra and I'm pretty confused by this question. A cook earns $10.20 per hour and time and a half for each hour worked over 40 per week. If she grossed $499.80 last week, how many hours did she work?
Please explain this to me, I'd really appreciate it. It's using (R + O = T) and Time and a half.

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

y=35

x=5
