In three math tests, you have scored 91,95 and 88 points. You are about to take your next test. Suppose you want to have an aver
age score of at least 90 points after all four tests. Explain a method you could use to find the score you must receive in order to average at least 90 points. The find the least score.
First you add up all the numbers then divide them by 3 then you get your answer: 91+95=186 186+88=274 274÷3=91.333333333and so on next you add 90 to 27540 274+90=364 and since there are 4 tests you divide 364 by 4 364÷4=91 Answer-91
