Solve, show the algebraic you use. Tammy has the following scores on her business law tests 92, 99, 84, 91. What score must she earn on her fifth test in order to have an A average? An A for her university starts at 90.
Answered by Ms. Sue
92 + 99 + 84 + 91 = 366

500 * 0.9 = 450

450 - 366 = ?



Answered by cody
Ms. Sue, wher did you come up with 500*0.9?
Answered by Ms. Sue
The total possible points for 5 tests is 500. 90% of 500 = 450. Tammy needs a total score of 450 to get a 90% average.
