The answer is 650 because 100 * 5 = 500 and 50 * 3 = 150 and 500 + 150 = 650
For questions like this just multiply the prices by how many they're buying and add all the numbers up and subtract by how much they have to begin with.
Example:
$34.99×2=$69.98
$16.50×3=$49.50
$3.75×4=$15
$69.98+$49.50+$15=$134.48
$134.48-$125=$9.48
