HELP ASAP!!!

Jenny is taking a two part exam. She wants a combined score of 85 points. On part one of the exam she scored 47 points. Using the variable P to represent the number of points she will score on part two of the exam, write an inequality that models the situation. Find the number of points she must score on part two to reach or exceed her goal of 85 points on the two part exam.

Answer 1

Answer:
`47 + p \geq 85`

Explanation:

Since, her total score = her score in first exam + her score in second exam.

According to the question,

Her score in first exam = 47

And, p shows her score in second exam.

Thus, her total score =
`47 + p`

For, reaching or exceeding her goal of 85 points in two exam.

Her total score ≥ 85

⇒
`47 + p \geq 85`

Which is the inequality that model the given situation.

`47 + p \geq 85`

⇒
`p\geq 38`

That is, she must score 38 score or more than 38 score in two part exam for reaching her goal.
