Okay, so here's the situation.
00:05
The candy maker wants to make a mix of 60 pounds of candy for $2 a pound.
00:11
Liquorish costs $1 .90 a pound and gum drops cost $2 .20 a pound.
00:15
And we want to know how many pounds of licorish and how many pounds of gum drops he's going to mix together.
00:20
So i chose variables to stand for the number of pounds of licorish and the number of pounds of gumgrops.
00:25
We have l and we have g.
00:27
We know that we add those together to get 60 pounds.
00:31
So that gives us one equation.
00:34
We also know that we could multiply the price per pound of licorice, $1 .90, times the number of pounds of licorice, plus the price per pound of gum drops 2 .20 times the number of pounds of gum drops.
00:45
And that will give us the total price, which will be $2 a pound times 60 pounds.
00:51
So here we have two equations with two unknowns.
00:54
And what i'm going to do with the first equation is subtract g from both sides and i get l equals 60 minus g...
