Question

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

Answer 1

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

Answer 2

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 :)
