Question 985988: Sariqs last test scores in history were 87, 85,91,and 88. What scores on his next test will give him an average of 90 or above? Write and solve an inequality. Answer by solver91311(24713) (Show Source):
In order to have a 90 or greater average on 5 tests, the sum of the scores of the 5 tests must be greater than or equal to 5 times 90. Add the scores already obtained and subtract that sum from the required 5 times 90. The result will be the minimum score required for a 90 average.
