Question

You are taking a science course in which there will be 5 tests. each worth 100 points, you have scores of 91, 94, 97, and 86 on the first 4 tests. you must make a total of 450 in order to get an A in the course. set up an inequality and solve it to find the sey of possible test scores that will give you an A.

9 + 94 + 97 + 86 + x ≥ 450
368 + x ≥ 450
368 - 368 + x ≥ 450 - 368
x ≥ 82

Answer 1

According to my calculations, the answer should be greater than or equal to 82

Answer 2

Explanation:

9 + 94 + 97 + 86 + x ≥ 450

368 + x ≥ 450

368 - 368 + x ≥ 450 - 368

x ≥ 82
