Stocking the Aquarium

Marina runs a public aquarium and has a budget of exactly \$100 to fill a new exhibit with exactly 100 animals. The supplier sells three things: reef sharks at \$10 apiece, sea snails at \$1 apiece, and guppies, which are only sold in bags of 8 for \$1 per bag. Marina insists the exhibit feature every species, so she needs at least one shark, at least one snail, and at least one bag of guppies. How many of each should she buy so that the animal count and the spending both land exactly on 100?
