Question

Jacob has test scores of 91, 94, 75, and 96 on his first four tests. What must he score on the final test to have an average of at least 82? Please give the calculated grade, don't worry about whether it is possible. Round to a whole number.

Answer 1

Answer:

54

Step-by-step explanation:

If x is the score of his final test, then by question

$\frac{91+94+75+96+x}{5} = 82$

therefore, ${356+x} = 5*82$

or, x = 54
