Answer:
4x + 5y ≥ 85
Step-by-step explanation:
If x is the number of true/false questions she gets correct, the total of points she will get for those x questions will be 4x.
If y is the number of multiple choice questions she gets correct, the total of points she will get for y questions will be 5y.
She needs at least 85 points to get an A, this means she needs 85 points of more on the exam.
Thus, the inequality would be 4x +5y ≥ 85.
