okay, so the bag of 30 lb candy will cost how much total?
the candy is worth 1.10 per lb, we have 30lbs of it, so therefore,
30lb * $1.10 per lb = $33.00

Does that part make sense?
yes it does
lets try it this way,
x + y = 30 lb
$1.5x + $0.90y = $33.00
Does that part now make sense?
Do you know how to solve it?
are we solving for x
Well, we have to equations, we will use the method of sub substitution to solve them. Since we have two unknowns (x and y), we need two equations to solve the system.
x + y = 30 lb Solve for x
x = 30 - y
Now we know what x is in terms of y, so lets sub that into our second equation.
$1.5y + $0.90x = $33.00
$1.5y + $0.90(30 - y) = $33.00 Now we must solve for y
