Kate's bill for this month for one bulb will be $1.8225
Further explanation:
Given
Old Bill for one bulb use = $7.29

The explanation is shown below:
1. You have that the triangles shown in the figure attached, are similar, therefore, you can calculate h as following:
(20-4)/h=h/4
16/h=h/h
2. Now, solve for h:
h²=64
h=√64
h=8
Answer:

A=#nickels, b=#quarters
5a + 25b = 410 total value
5(a + 5b) = 410
a + 5b = 82
a + b = 30 total no. of coins
subtracting . . . 4b = 52
thus b = 13 and a = 17
13 quarters and 17 nickels = 13*25 + 17*5 = 410 = $4.10
