Question

Ana bowled 144 and 176 in her first two games. What must she bowl in the third game o have an average of t least 150 for the three games?

Answer 1

Let's see what she needs to obtain an average of 150

 

(144+176+x)/3 = 150

320 + x = 450

x = 130

 

to obtain an average of 150 or higher she must bowl at least 

130 on her third game
