Henri’s potato vine is growing like crazy! When he planted it, it was 15 inches long. Two weeks later, it was 22 inches long. Four weeks after that, it was 36 inches long. Write an equation to represent this situation.
Every week it grows 7 total inches. So, "x" stands for week. The equation "1x = 7" means 1 week equals 7 inches. This is the simplest equation to write this problem.
