You are a manufacturer of a certain item. You’ve calculated that you can sell 80 of these items for $5 each and you can sell 60 of these items for $8 each.
Assuming this relationship is linear, write an equation that relates cost to the number of watches you make

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
