Agrading machine can grade 96 multiple choice tests
in 2 minutes.

Remember that when posting questions here, you have to write the complete question in order to get a great and correct answer. Anyway, I found the complete question and is as follows:

A grading machine can grade 96 multiple-choice tests in 2 minute. How long will it take the machine to grade 300 tests?

So this problem can be used by using proportions. So we have that a grading machine can grade 96 multiple-choice tests in 2 minute. So we need to find the time (t) it takes the machine to grade 300 tests. So:

Hence, it would take the machine  6.25  minutes, that is, 6 minutes and 15 seconds to grade 300 tests.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
