1431 total strings of lights.

Step-by-step explanation:

First, we need to set up a proportion for this problem.

480 deficient = 162 deficient

4,240 total x total

use the "butterfly" method: multiply each diagonal of the proportion and set them equal to each other.

162 * 4,240 = 480x

686880 = 480x

686880/480 = x

x = 1431 total strings of lights.
