John must have at least 289 test points to pass his math class. He already has test scores of 72, 78, and 70. 72 + 78 + 70 + x = 289 will tell him at least how many more points he needs to pass the class.

Solution:

72 + 78 + 70 + x = 289

220 + x = 289

x = 289 - 220

x = 69 more points he needs to pass the class.
