To solve this, set up a proportion where X is the amount that 120 lawn mowers would cost. It would look like [tex] \frac{40}{4776}=\frac{120}{x} [/tex].
Then cross-multiply to get 40x = 120(4776) or 40x = 573120. Now divide each side by 40 to isolate the variable.
X = 14328.
120 lawn mowers would cost $14,328.
