Jacob put 3,0 on a coordinate plane, he moves 1 unit east and 3 units north, and places a pin at 4,3, he continues to move 1 unit east and 3 units north 12 more times, placing a pin each time, where would the last pin be placed?
Since Jacob moves 1 unit east and 3 units north every time, after moving 12 more times, he would have moved a total of 12 units east and 36 units north. Therefore, the last pin would be placed at (3 + 12, 0 + 36) = (15, 36).
