I think the answer is $11,340
We can see that both triangles are identical to each other, except that the second is bigger than the first. We can also see that the second triangle's side lengths are one unit more than the first. Let's take the top line as an example: Figure 1 is 3 units long while Figure 2 is 4 units long. To find the scale factor, you divide the shorter length by the longer length and in this problem, you would get 3/4, or 0.75% (which is A).

The system of equation
y=8x and y=2x
To solve this using graphical method
The solution is the point of intersection of the two-lines
As shown from the graph above, the solution is (0,0)
54 nickels and 27 dimes
1 dime = 10 cents = $0.1
1 nickel = 5 cents = $0.05
setting up 2 equations
let n = amount of nickels and d = amount of dimes, then
n + d = 81 → (1)
0.05n + 0.1d = 5.4 → (2)
multiply (2 ) by 10
0.5n + d = 54 → (3)
subtract (3) from (1) to eliminate d
0.5n = 27 ( divide both sides by 0.5 )
n = = 54
substitute n = 54 in (1)
54 + d = 81 ( subtract 54 from both sides )
d = 27
Mary has 54 nickels and 27 dimes
To find the mean, we add up all the numbers then divide the sum by how many numbers there are
12 + 15 + 14 + 12 + 4 + 8 = 65
65 ÷ 6 = 10.833333
