Answer:
If both sides are equal
Step-by-step explanation:
If both sides are equal and are the same in both sides of the equation, than it is a solution.

Answer:
$468.09
Step-by-step explanation:
first we must calculate the expected future value of the engine overhaul:
($390 x 10%) + ($570 x 30%) + ($750 x 50%) + ($790 x 10%) = $39 + $171 + $375 + $79 = $664
now we must determine the present value of $664 using a 6% interest rate:
PV = FV / (1 + r)⁶ = $664 / 1.06⁶ = $468.09
