Let p be the price, and N be the sales
If there's a linear relationship,
N = mp + b
Now plug in what you know:
80 = 5m + b
60 = 8m + b
20 = -3m
m = -20/3
b = 340/3
so,
3N = -20p + 340
If there's a linear relationship,
N = mp + b
Now plug in what you know:
80 = 5m + b
60 = 8m + b
20 = -3m
m = -20/3
b = 340/3
so,
3N = -20p + 340
