<h2>There are 45 houses on the left and require 95 plates, while there are 44 houses on the right and require 94 plates</h2>
Step-by-step explanation:
Houses are numbered from 1 to 99. So, there are 99 houses. Odd-numbered houses are on the left. So, there are 50 houses on the left, while there are 49 houses on the right.
For houses on left : The houses are numbered 1, 3, 5, 7, 9, 11, 13..... 97, 99
So 5 houses( 1, 3, 5, 7, 9) require only one plate for numbering, while the remaining 45 houses require 2 plates each. So total number of plates = =
plates.
For houses on right : The houses are numbered 2, 4, 6, 8, 10, 12, 14.... 96, 98
So 4 houses( 2, 4, 6, 8) require only one plate for numbering, while the remaining 45 houses require 2 plates each. So total number of plates = =
plates.
∴ There are 45 houses on the left and require 95 plates, while there are 44 houses on the right and require 94 plates.
Percentages are out of 100. So we'll multiply by 0.85 to represent the 15%
To find the y points on the graph we can use f(x) =
We'll input 1-5 for x to find y:

Therefore the answer is a graph of exponential function going down from left to right in quadrant 1 through the point 0, 40 and approaching the x-axis.
