Given table is :
m d
1 80
2 160
3 240
4 320
We can see that the difference is common for all months.
The cost(d) of 1 month is $80.
So, cost for m months will be = 80m
Therefore, the equation for the number of dollars,d, that you pay for your karate classes if you take classes for m months is:
[tex]d=80m[/tex]
