1. The first choice would be better because:
$55.49 + $.25(80) = $75.49
$71.30 + $.07(80) = $76.90
2. The first choice would be better because:
$55.49(2 days) + $.25(50) =
$123.48
$71.30(2 days) + $.07(50) =
$145.80
3. The second choice would be better because:
$55.49 + $.25(75 + 15) = $77.99
$71.30 + $.07(75 + 15) = $77.60
