if n houses have k windows, write an expression to represent the number of windows for n + 1 houses
n+ 1 = 4+4k
There are on average k/n windows/house
So, n+1 houses have k + k/n windows
where'd you get the 4?
W = (n+1)/n * k = (kn+k)/n = k +k/n.
The 4 comes from each house having 4 windows according to the image above!
To find the number of windows for n + 1 houses, we need to consider the given information: n houses have k windows.
If n houses have k windows, we can express that as n = k. This means each house has k windows.
To find the number of windows for n + 1 houses, we can simply add k to the existing number of windows for n houses. Since each house has k windows, the total number of windows for n + 1 houses would be (n + 1) * k.
Therefore, the expression to represent the number of windows for n + 1 houses would be:
(n + 1) * k
