It's not hard if remember a couple of things that you should have learned \before you ran into this problem. Here they are:
1). ' 10% ' means 10/100 , or 0.1
2). In middle school math,"of" almost always means "times".
Now that you know those two things, you can use them to re-write the problem:
" 10% of 120 " means " <em>0.1 times 120</em> ".
I'm sue you can solve that.

Answer:
$12.25
Step-by-step explanation:
1.6 ounces of cinnamon sticks and 9.4 ounces of cocoa. The equation for this would be 3.25s + 0.75c = t, where s is the amount of cinnamon sticks, c is the amount of cocoa, and t is the total price.
3.25s + 0.75c = t
3.25(1.6) + 0.75(9.4) = t
5.2 + 7.05 = t
12.25 = t
The total price is $12.25.
Given the data
X, ...rankX.....Y.....rankY......d=rx-ry........d²
4.........4...........-5......4................0..............0
53.......3.........-1........3................0...............0
86.......2.........13.......2................0................0
162......1..........16.......1.................0...............0
Then, using the rank correlation formula
p = 1 — 6•Σd² / n(n²—1)
p = 1 - 6• 0 / 4(4²-1)
p = 1 - 0
p = 1
So, the rank correlation is 1, this means that the two variables being compared are monotonically related, even if their relationship is not linear.
Formula for the volume not a cone=πr2H. π=3.14. R=12×2=24. H=16. 3.14×24=75.36. 75.36×16=1205.76. ANSWER: 1205.76
