How many hot dogs were sold at the fifth football game?

answers:

568

570

574

598

Answer 1

To find the number of hot dogs sold at the fifth football game, we can use the formula for the mean:

Mean = (Sum of all numbers) / (Number of numbers)

We know that the mean is 573, and the sum of the hot dogs sold at the first four games is 523 + 604 + 544 + 596 = 2267.

So, substituting these values into the formula, we have:

573 = 2267 + X / 5

573 * 5 = 2267 + X

2865 = 2267 + X

2865 - 2267 = X

598 = X

Therefore, 598 hot dogs were sold at the fifth football game.

The correct answer is 598.
