Answer:

C

Step-by-step explanation:

Given

f(x) = 3x - 40 and f(x) = 8 , then equate the right sides, that is

3x - 40 = 8 ( add 40 to both sides )

3x = 48 ( divide both sides by 3 )

x = 16 → C

USPshnik [31]

Answer:

300 dollars

Step-by-step explanation:

Let the original amount = x

x - 2/5x  was what his mother's share looked.

5/5 x - 2/5 x

3/5x is what is left.

3/5 x - 1/4 * 3/5 x - 2/3x * 3/5 = his sister's share and his brothers

3/5x - 1/4*3/5 x - 2/3 * 3/5 = 15

3/5x * (1 - 1/4 - 2/3) = 15

3/5 x 5/60 = 15

15 / 300 * x = 15

1/20  x = 15

x = 15 * 20

x = 300
