Answer:
Step-by-step explanation:
this seems like substitution
If so its the first part is 12x6
second part is 35 x 6
third part is 56 x 6
Let G=cost of gold ticket.
Silver ticket costs
S=G/2+7, and
S=6G/5-14
Equate both,
6G/5-14=G/2+7
simplify
6G/5-G/2 = 7+14
12G/10-5G/10=21
7G/10=21
Cross multiply
G=10*21/7=30 => Gold tickets cost $30 each.
S=G/2+7=30/2+7=15+7=22
Silver tickets cost $22 each.
The first 100 gold ticket purchasers will therefore save $30-$22=$8 each ticket.

To solve for the total number of 12 – flag signals Sally
can make, we need to make use of the formula:
total flags = d! / (a! b! c!)
Where,
d = is the number of flags to create a signal = 12
a = number of red flags = 5
b = number of green flags = 3
c = number of white flags = 4
We can observe from the equation that the individual
number of flags is factored out (or divided from) that is because all the 5 red
flags are similar, all the 3 flags are similar and all 4 flags are similar.
Going back into the equation, by substituting and
calculating:
total flags = 12! / (5! 3! 4!)
total flags = 27,720
<span>Therefore there are about 27,720 different 12-flags
signals.</span>
3x+2(x-24)=462
3x+2x-48=462
5x=562+48
5x=510
x=510/5 102 boxes of pecans
102-24=78 boxes of walnuts
Hopefully this makes since! Feel free to ask questions
