Your average score is currently (61+70+99+70)/4 = <<(61+70+99+70)/4=75>>75
To get a B, you need an average of at least 80, so you need a score of 80-75 = <<80-75=5>>5 higher on your last test.
Thus, you need a minimum score of 70+5 = <<70+5=75>>75 on the last test to get a B. Answer: \boxed{75}.
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 receive 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.
