Answer:
15
Step-by-step explanation:
you can think of this table as a data set--and you could even write it out
5, 5, 5, 10, ......... 20, 20 {I did not write it out in full of course}
so, when thinking about the range, we can think of it as a range of our data set.
We find the range of a data set by finding the difference between the highest and lowest values
So, we know that our highest data value (amount) is 20, and the lowest is 5:
20 - 5 = 15
meaning that there is a range of $15 in this data set of allowance amounts
hope this helps!! have a lovely day! :)
