Question

There were five football games at school. The number of hotdogs sold at the first four games were 523 604 544 596

The mean number of hotdogs sold at five games was 573.
How many hotdogs were sold at the fifth football game?

Answer 1

Total sold at 4 games: 523 + 604 + 544 + 596 = 2,267

Mean is the average, multiply mean by total games to find total sold:

573 x = 5 = 2,865 total

Now subtract for the amount sold at the 5th game:

2865 - 2267 = 598 hotdogs sold at 5th game.
