To get on the top players list , don needs to have a minimum average score of 225 after playing four games. His scores on his first three games were 192, 214, and 250.
What is the minimum score don needs to earn on his fourth game ?
average must be 225 or more 4 games so [tex] \frac{score1+score2+score3+score4}{4} \geq 225[/tex] score1=192 score2=214 score3=250 score4=? so [tex] \frac{192+214+250+?}{4} \geq 225[/tex] [tex] \frac{656+?}{4} \geq 225[/tex] times both sides by 4 to clear fraction 656+?≥900 minus 656 from both sides ?≥244
