there were 5 football games playing at a school. the number of hot dogs sold at the 4 first games are shown. 523, 604, 544, 596. the mean number of hot dogs sold are 573. how many hot dogs were sold in the fifth football game?

Question

darkknight · Answer

You want to set up an eqn, where x is the number of hot dogs sold in the 5th game.
So the mean is basically the average number. So
$$573 = (523 +604+544+596+x)/5$$

Can you solve for x from here?
