Question

PLS NEED HELP ASAP

Answer 1

Answer:

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 :)
