Answer:
D
Step-by-step explanation:
10*20=200
200 + 1020= 1220
Works for the first one
20*20=400
400+ 1020=1420
Works for the second one
30*20=600
600+1020=1620
Works for the third one, and all the others one so forth.
You take the number on the left (10, 20, 30, 40, 50, 60, 70) and times it by 20, replacing the x in the equation with the number on the left side of the table. Then you add the number from said equation to result of the multiplication from the first step.
