The math problem isn't that difficult. I didn't think marijuana was that cheap, though. At that price, a container of dimes and quarters would be worth more than the same weight of marijuana.
10 grams for $1? Where is Bartholomew's dispensary located? That's damn cheap. 10 grams would cost you anywhere between $50 and $200 in Oklahoma dispensaries right now. Prices are high because there isn't a lot of product out there yet and growers are asking astronomical prices for flower and concentrates but it will soon be harvest time and there will be a glut of product on the market. There are dozens of dispensaries about to be open. Tulsa alone dispensaries that are licensed by the OMMA. Some of these dispensaries will never open and quite a few still haven't opened yet. New stores are opening all the time but there are still a lot of dispensaries that are marked "Coming soon!" on Weedmaps. The glut of product combined with intense competition should drive prices down. There are only about 40,000 registered patients in the state which makes a small number of potential customers. It's going to be interesting to see from such a close vantage point.
I dunno about your school, but in mine, everything in word problems involving money was priced absurdly high or low, probably out of a desire to not want to revise the problems between textbook editions to track inflation. I considered making the prices more realistic, but I figured a thorough survey of weed prices probably isn't something someone with no OMMA card should have in their search history.
24. Bartholomew purchased one kilogram of marijuana for $25.
a) If Bartholomew divides the weed into 10-gram bags, how many bags will he have?
b) If Bartholomew sells each bag for $1, what will his profit margin be on each bag?
c) If Bartholomew sells all of the bags, how much profit will he make altogether?
Be sure to show your work on a separate piece of paper.
Are you trying to weed out the math experts here?

I'm sure the potheads here can figure this one out pretty quickly.
a) 100
b) 75 cents
c) $75
The answer to 24b is actually 75% (margin is expressed as a percentage). 75¢ is the markup. Half credit.
When I first learned that there were cops in schools that stayed there all day, it blew my mind. I can't imagine what it must be like having a cop patrolling your school hallway.
In my experience, they didn't really do much other than occasionally interrupt classes to sit up at the front and BS with the teacher.
