Question

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 average 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.

Answer 1

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

Answer 2

Answer:

You have to add up all the numbers then divide them by 3 and you will get your answer:

91+95=186 186+88=274

274÷3=91.333333333 etc.

then you add 90 to 27540

274+90=364

and because there are 4 tests you divide 364 by 4

364÷4=91

Your Answer-91
