Ordering Ant Eggs

Congratulations, you helped the first mate get his GED! But now you've got another problem--your pet marsupial moles are almost out of food! Their favorite meal is ant larvae so you'd like to order more for them. However, you don't know how much they cost. The first mate ordered the previous two shipments but he doesn't remember how much they cost per pound.

However, he does have his credit card statements which show the first batch was $12.25 and the second batch was $21.75. He also remembers that the first batch was $2 a pound more expensive because of extra shipping costs. And the second batch was $2 per pound cheaper because he picked it up at the warehouse himself. And he knows that he received five pounds total for the last two shipments. From this information, figure out the regular price (in dollars per pound) for ant larvae.

Good luck!

New Angler Fish

Congratulations, you got a friend for Jerry and now they share a new habitat. But the first mate still has more problems for you to help him with. If you help him with the problems below, he'll show you a picture of a new species of Angler Fish discovered in June of this year!

Good luck!
