Question

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

A. 72 + 78 + 70 + x ≤ 289   B. 72 + 78 + 70 + x > 289   C. 72 + 78 + 70 + x < 289   D. 72 + 78 + 70 + x ≥ 289

Answer 1

let x be the number of points he requires to pass

the total sum of all his test scores would be 72 + 78 + 70 + x

since he needs at least 289 points in order to pass, this sum must be equal or greater than 289

therefore, your answer is D

hope that helps :)
