I’m personally not to good at adding fractions so I turned 1/10 into 0.1
Then I divided 268.4 by .1 and got 2,674.
2.41+6(0.41)+(lb-7)0.39=7.99
2.41+2.46-2.73+0.39lb=7.99
0.39lb=5.85
lb=15
The package of books weights 15 pounds...

For every 5 cashews, there are 6 peanuts and 7 almonds.
Means: Cashews:Peanuts:Almonds = 5:6:7
Sum of ratio = 5 + 6 +7 = 18
Cashews = (5/18) * 270 = 75
Peanuts = (6/18) * 270 = 90
Almonds = (7/18) * 270 = 105
So how many more what are there than peanuts?
The number of that nuts Minus the number of peanuts.
= Number of that nuts - 90
; otherwise 
is undefined as long as we're only looking for real solutions.
