I believe it's 4. 1/2 = 1/4
so, 1/2 + 1/2 + 1/2 + 1/2 would be 4/4...
Your rows would be $0.90 Chocolate, $1.20 Chocolate, and the Total Chocolate Mix, and your columns would be the Amount of Chocolate in #s and the Total Costs
(This is the best I can do coming up with a grid)
________________amt (#)_________total costs
$0.90_____________10______________9.00
$1.20______________x______________1.20x
Total Mix_________10+x_____________9+1.2x
Using this grid, you see that 10+x=9+1.2x so solve for x
10+x -x=9+1.2x -x
10=9+.2x
10 -9=9+.2x -9
1=.2x
1/.2=(.2x)/.2
x=5, so you need 5lbs of the $1.20 chocolate to produce a mixture worth $1.00
<span> dropped 7 degrees means "-7"
</span><span>rose 9 degrees means "+9"
</span><span>dropped 2 degrees means "-2"
</span><span> dropped 5 degrees means "-5"

-7+9-2-5=-14+9= - 5
Answer is -5.
