Lets gather some info...
white cars (level 1) = 230....(level 2) = 120...total of (230 + 120) = 350
silver cars (level 1) = 110....(level 2) = 70...total of (110 + 70) = 180

so there are (350 - 180) = 170 more white cars then silver cars.

A is final amount
P is principle amount
r is rate
n is compounded rate
t is time

Step-by-step explanation:

Step 1: Define

Identify given variables.

P = $47,323.15

r = 0.05

n = 1

t = 3

Step 2: Find Interest

[Compounded Interest Rate Formula] Substitute in variables:
$\displaystyle A = 47323.15 \bigg( 1 + \frac{0.05}{1} \bigg) ^{1(3)}$
Evaluate:
$\displaystyle A = \boxed{54782.5}$
