Question 576332: Jackie has grades of 73 and 85 on her first two algebra tests. If she wants to have at least a 72 average, what scores can she make on her third test? Answer by solver91311(24713) (Show Source):
If you want a particular average on three tests, then the total of your three test scores has to be three times the desired average. Multiply 72 by 3 and then subtract 73 and 85 from the product. The result is the minimum score to achieve a 72 average.
