Answer:
Hope this helps, I didn't know if that seventy was positive or negative so I did both scenarios.
Step-by-step explanation:
The range is the difference between the largest and smallest number
-80 -72 -69 -66 -66 -61 70
If you mean for this seventy to be positive then the range is 150
-80 -72 -70 -69 -66 -66 -61
If it is not positive and you forgot to put the negative sign then your answer is 19
