Answer:
$ 3199.0
Step-by-step explanation:
Let the number of shares of ABC = x
and XYZ = y
writing each as a linear equation
32 x + 23 y = 10100 equation 1
1.2 x + 1.4 y = 540
1.4 y = 540 - 1.2 x
y = ( 540 - 1.2 x) / 1.4
substitute for y in equation 1
32 x + 23( 540 - 1.2 x) / 1.4 = 10100
32 x + 8871.43 - 19.71 x = 10100
collect the like terms
32 x - 19.71 x = 10100 - 8871.43
12.29 x = 1228.57
x = 1228.57 / 12.29 = 99.97
the amount of money to be invested in ABC shares = 99.97 × $ 32 = $ 3199.0
Answer:
-4x - 3 = -8
Step-by-step explanation:
On our left, we have -x in 4 places = 4(-x) = -4x
And on the left, we also have -1 in 3 places = 3(-1) = -3
Altogether in our left, we have: -4x +(-3)
That is: -4x - 3
On our right, we have -1 in 8 places, which is 8(-1) = -8
Therefore, the equation that represents the model would be:
-4x - 3 = -8
