Answer:

  a) P = 10(8(V -5)) -150

  b) P = 80V -550

  c) P = 3450

Step-by-step explanation:

a) Use the expression for B to substitute into the equation for P:

  P = 10(8(V -5)) -150

__

b) Eliminate parentheses and collect terms.

  P = 10(8V -40) -150

  P = 80V -400 -150

  P = 80V -550

__

c) Substitute 50 for V and do the arithmetic.

  P = 80·50 -550

  P = 3450
