To determine which is the better buy, we need to calculate the cost per golf ball for each pack.

For the 5 pack of golf balls:
$3.49 / 5 balls = $0.698 per golf ball

For the 7 pack of golf balls:
$5.05 / 7 balls = $0.721 per golf ball

Based on these calculations, the 5 pack of golf balls is the better buy as it has a lower cost per golf ball.
