Question

Question 14 Yoko's final exam has true/false questions, worth 4 points each, and multiple choice questions, worth 5 points each. Let x be the number of true/false questions she gets correct, and let y be the number of multiple choice questions she gets correct. She needs at least 85 points on the exam to get an A in the class. Using the values and variables given, write an inequality describing this.

Answer 1

4x + 5y ≥ 85

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.
