Question

the number of computers sold at an electronics store for each day of a week is shown in the dot plot below.
what percent of computers sold on the weekend were sold on saturday?
what percent of computers sold monday through friday were sold on friday?
which percent is greater?
saturday accounted for □% of the total computers sold on the weekend.
friday accounted for □% of the computers sold monday through friday.

Explanation:

Step1: Count weekend computers sold

Saturday: 7, Sunday: 3. Total weekend: $7 + 3 = 10$

Step2: Calculate Saturday's weekend percentage

$\text{Percent} = \frac{7}{10} \times 100\% = 70\%$

Step3: Count weekday computers sold

Monday: 6, Tuesday: 8, Wednesday: 9, Thursday: 5, Friday: 11. Total weekday: $6 + 8 + 9 + 5 + 11 = 39$

Step4: Calculate Friday's weekday percentage

$\text{Percent} = \frac{11}{39} \times 100\% \approx 28.21\%$

Step5: Compare the two percentages

$70\% > 28.21\%$

Answer:

Saturday accounted for $70\%$ of the total computers sold on the weekend.
Friday accounted for $\approx 28.21\%$ of the computers sold Monday through Friday.
The percentage of weekend computers sold on Saturday is greater.
