Question

Rita's final exam has true/false questions, worth 2 points each, and multiple choice questions, worth 5 points each. Let x be the number of true/false questionsshe 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

We have

x= number of true/false question

y=number of multiple questions

2x is the number of points for the true/false questions.

5y is the number of points for multiple questions.

Therefore the inequality will be

`2x+5y\ge85`

The sum of the points needs to be greater than or equal 85 to get a A
