Question

To make the bowling team. Jacques needs a three-game average of 160. If he bowled 141 and 162 for the first two games, what score S must be obtained in the third game so that his average is at least 160?

Answer 1

(141 + 162 + S) / 3 = 160

(303 + S) / 3 = 160

101 + S/3 = 160
-101 -101
S/3 = 59
*3 *3

S= 177

Jacques needs at least a 177 to get a 160 average
