Answer: The company will make 720 dollars (I dont know the percentage out of that though).
Step-by-step explanation: 1.10 times 1000= 1100. 35 percent of that is 385 dollars worth to charity or 350 lapel pins. 1000 minus 350 equals 650. 650 times .6 equals 390. 390 times 3 dollars= 1170 dollars. 650 times .4 = 260. 260 divided by 2 = 130, 130 times 5 dollars equals 650 dollars. 650 plus 1170= 1820. 1820-1100= 720.
Last Question
Because this may not be the question you want, I'll omit the first step which should be done with latex. The key to all of these except C is to invert the second fraction (turn the second fraction upside down) and multiply.
A

=(6*-2) / (5*3) = - 12/15 = -4/5
B
= (7*5) / (4*3) = 35 / 12 = 2 11/12
C
Impossible to do 4/0 cannot be done.
D

= (-2*-4)/(3*5) =
8/15
The answers are as follows:
Box 1) D
Box 2) .02D
Box 3) D + .02D
I would add 24 and 36, to make 60, then I would tack on 13 and get 73.
Well, if the elevation is 45 degrees, the height of the tree and the distance to the truck are the same.
The elevation is more than that, so the distance to the truck is less than the height of the tree.
The only answer that reflects that is D.
