Answer:
<u>The original cost of the printer before adding the tax was $ 173.98</u>
Step-by-step explanation:
Total cost of the color printer, including tax = $ 186.16
Tax rate = 7%
Original cost of the printer, before tax = x
For answering the question, let's use the Rule of Three Simple, this way:
Percentage Value
107% 186.16
100% x
x * 107 = 186.16 * 100
107x = 18,616
x = 18,616/107
x = 173.98
<u>The original cost of the printer before adding the tax was $ 173.98</u>
1. IQR = Q3 - Q1 = 35 - 20 = 15
A. 15
3. The ages include 20 and 25 so A and C are out, and the ages are between the two ages
B. a >= 20 and a <= 25
4. With the addition of 30, there are now 14 dots. Therefore, the median will be the mean of the 7th and 8th dots from least to greatest on the number line. In this case, it would still be 22.
C. The median would stay the same.
(34-12)÷2+7
22÷2+7
11+7
18
