anonymous one year ago Malina has to bowl four games in her league. She bowled a 149, 162, and a 152 in her first three games. She wants to have an average score of 154. What score does she need in her fourth game? 152 153 154 155

see which one works, by finding the mean for each option

So what we want is $\large \bf Average~=~154$ What we know is the score of 3 of the games. That means we can construct this: $\large \bf \frac{149+162+152+x}{4}~=~154$ Now solve for x :)
