Leo’s dad brought home some bagels and muffins. Each bagel cost $0.90 and each muffin cost $0.80. Altogether he brought home 9 items for a total cost of $7.60.

Leo's dad bought 4 bagels and 5 muffins.

Step-by-step explanation:

The total cost was 7.60, and had 9 items. I figured that the solution of           (__ x 0.9) needed to end with 60 cents.

4 x 0.9 = 3.6

5 x 0.8 = 4.0

3.6 + 4.0 = 7.60.

Total of 9 items, adding up to 7.60.

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.
