PLS NEED HELP ASAP
Jessica is getting ready for college. She needs to have an overall grade of 85 in her Math class to qualify for the college that she wished to attend. Her math grade is based solely on her scores on 6 exams. On the first 5 exams her scores were 87, 81, 85, 90, 78. Write an inequality that represents her prediction for the grade that she needs to get on the sixth exam. What minimum score does she need to get on her last test to qualify for college?

Jessica needs to score at least 88.2 (or 88) on her last test.

Step-by-step explanation:

So, her average so far is the sum of the five scores divided by the number of tests she has taken so far.

(87 + 81 + 85 + 90 + 78)/5 = 84.2

(87 + 81 + 85 + 90 + 78)/5 < 85 :(

She will not get into that college if she doesn't increase her average on the last test.

85 - 84.2 = 0.8

0.8(5) = 4.0

On her last test, she needs to score 4 points higher than her current average in order to get into the college.

84.2 + 4 = 88.2

Hope this helped :)

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
