The cost per game for Jennifer can be calculated by dividing the total amount she paid by the number of games she bowled: $14.00 / 2 games = $7.00 per game.

The initial shoe rental cost can be calculated by subtracting the cost per game from the total cost for each person:

For David: $18.50 - ($6.17 x 3) = $18.50 - $18.51 = $0.50

For Jennifer: $14.00 - ($7.00 x 2) = $14.00 - $14.00 = $0.00

So, the initial shoe rental cost is $0.50 for David and $0.00 for Jennifer.
