Question

Tony has scored 23 , 25 , 21 , and 18 points in his four basketball games so far. How many points does he need to score in his next game so that his average (mean) is 21 points per game?

Answer 1

17

Step-by-step explanation:

firet we need to multiply the 21 by 5 so we know what he should get in total. then we can add all the points together which is 87. next we can minus 87 from 104(21 x 5) which is 17. this means tony must get 17 points in hist next match to get a average of 21.
