you must have an average score of at least 80 to get a B on your report card. You have scores of 61,70,99, and 70. What is the minimium score you must get on the last test to get a B on your report card?

the minimum score you can make and recieve an 80 is 100

The minimum score does not require an inequality.

Mean (average) = Sum of scores/N (number of scores)

80 = (61 + 70 + 99 + 70 + X)/5

Solve for X.

I hope this helps a little more. Thanks for asking.
