# Math needs to be more interesting: "David is caught with both pot and crack. David's pot is valued at $310 an ounce and his crack is valued at $450 an ounce. David had 3 times as much pot as he had cocaine. In total, David had $54,000 worth of drugs. Write and solve a system of equations to determine how many ounces of each drug he had. Estimate how much prison time he will receive",

**right**! Vote on the post to say if you agree or disagree.
yolo

310x+450y=54,000

3x=y

About 32.5 ounces of pot and 97.5 ounces of crack.

I was curious :>

if i were ever a drug dealer, you would get free crack

It should be 3y=x

Yeah, you're right. Silly mistake on my part. I was in seventh grade back when I did this. Sorry!

Haha no problem, it's an easy mistake to make.

That's wrong, like the guy above said, its 3y=x which changes whole answer.

first off, a dude with pot is less likely to have crack....but yeah stoners use a lot more math than they are given credit for.

310y+450x=54000

y=3x (He had three times as much pot as crack)

310(3x)+450x=54000

1380x=54000

x=39.13

y=3(39.13)

y=117.39

He had about 117 ounces of pot and 39 ounces of crack

Steps if you are curious.

Let, C represent Cocaine, and let P represent Pot

since:

a) 3C = P

and

b) 310P+ 450C = 54,000

sub a into b

310(3C) + 450C = 54,000

1380 C = 54,000

C = 39.13

sub C into a

3(39.13)= P

117.39= P

Therefore, David has 39.13 ounces of crack and 117.39 ounces of pot

For part b) you'd have to let me know where he lives so I could complete it.

Also depends on if this is his first offense or not

There is 1/3 the amount of crack as there is pot so it should be 3C=P, not 3P=C.

K, let me fix that then

You're wrong, it's 32 and 97, like the guy above said. L2math.

How can David have three times as much pot as crack, but at the same time have less pot than crack?

I like that you changed that awful wording. Lol anyway, you're right, sorry, I believe I made the same mistake as the first guy. And he meant the pot was the 97 and the other was 30 btw.

He said 3x=y but it was x=3y

But once you change it to x=3y it affects all the rest of the work, so you can't just switch the two answers.

Yeah, exactly.

I'm glad to know I was actually making sense. And I recognize that it's an incredibly easy mistake to make.

We're all such nerds, man.

Damn, I thought all the cool kids had mathematical arguments on the internet. I guess I'm not doing this right...

I probably would have passed if we did it this way lol

The estimating how much prison time they'll get is what got me lol.

My math teacher for my SAT class gave us a problem like this . . .

She wanted to know how much time she was looking at for her court appearance the next week.

This is what I thought of when I read this post.

"John, Jack and Jim lit up their pipes after dinner and began blowing smoke rings. By the time they were finished, they had blown a total of 6437 smoke rings. If John blew 52 smoke rings and Jack blew 3896 smoke rings, how many smoke rings did Jim blow?"

THIS has some interesting word problems at the end.

Dudeee I love Hank!

And John, of course.

My math teacher gave my class a math problem that had to with giving a drug dealer money.
