Answer: Mode
<u>Step-by-step explanation:</u>
The given data set is: 10, 10, 12, 13, 15
Mean is the average - find the sum of the data set and divide by the number of terms in the set: 
Mean = 12
Median is the middle term (when the data set is ordered from least to greatest).
Median = 12
Mode is the term that appears the most.
Mode = 10
Since you want to show that the prices are low, you would choose the lowest value. 10 is lower than 12, so the Mode is lower than either the Mean or the Median.
4 times 2= 8. so, 4times k2 = k8. To understand this better, imagine that k equaled 2. That would make the expression above = (2x2)4, which would equal 16. However, since we don't know the value of k, we have to use the numbers that we already have, It would be like solving the expression: (2x2)4 without multiplying the first 2. It would then be 2x8. So, we just simplified it, we didn't solve it.
