g. lowest price is 0.719 beer root/pizza

Explanation:

Alyssa takes 3 hrs to brew a gallon of root beers and 2 hrs to make a pizza

Crystal takes 7 hrs to brew a gallon of root beer and 5 hrs to make a pizza

Alyssa make 1 gallon/3 hrs = 0.33 gallons/hr of beer, and the same way makes 0.5 pizza/hr

Crystal makes 0.143 gallon/hr of beer, and 0.2 pizza/hr

for Alyssa, 0.33 gallons/hr = 0.5 pizza/hr, therefore

1 gallon of beer = 0.5/0.33 = 1.51 pizza

for crystal, 1 gallon of beer = 0.2/0.143 = 1.39 pizza

price of pizza:

Alyssa = 0.662 root beer/pizza

Crystal = 0.719 root beer/pizza

d. automatic stabilizers.

explanation:

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
