Ben bowled 154 and 188 in his first two games. What must he bowl in his third game to have an average of at least 170?
Ben must bowl at least
______ in his third game in order to have an average of at
least 170.
to calculate average, you simply add all the data, and divide it by the number of data. so in this case, let the third game be y. so, (154 + 188 + y)/3 = 170 154 + 188 + y = 510 y = 168 so he must bowl at least 168 in his third game
