    Stephen earned scores of 88 points, 94 points, 89 points, and 85 points on four tests. What is the lowest score he can get on the fifth test and still finish with an average score of 90 points?

    Let x is the required score, then \(\dfrac {88+94+89+85+x}{5}=90\) solve for x, please

    An average is all divided by the number of numbers. So we have 88 89 94 85. This would be (88+89+94+85+x)/5 = 90
