Choose the inequality that describes the following problem. Mark wants to get at least a 90% for his marks in his science class. So far, he has
taken five 100-points tests, and he scored 460 points total. The final test is 150
points. What must he score to finish the class at his goal of at least 90%?

Step-by-step explanation:

So first we have to find out the total number of points possibleSo he took 5 tests each with a max score of 100 points, so that's 500 points totalThe final test will be 150 points, so his whole grade is out of 500+150= 650 pointsHe has already scored 460 of those 650 pointsNow how much must he get in the least, on the last test in order to make 90%?Now we need to find what 90% of 650 points isso Then we ask ourselves, how much must we add to 460, to get 585 points? 585-460= 125 pointsSo Mark needs to get either 125 points or more on the next test to make 90% or moreNow let's say the letter means whatever grade number Mark gets on his next testThis number must not be less than 125, so it must be either equal to or greater than 125 pointsSo
