Question

For the first four basketball games, the concessions stand sold 600 hot dogs. If the rate remains, how many hot dogs will be sold in 10 games?

Answer 1

600 dogs/4 games = x dogs/10 games
600/4 = x/10
x = 1500

or

number of new games = 10/4 or 2.5 times old games,
so hot dog sales must be in the same ratio
2.5(600) = 1500
