Calculating the Total Number of Streetlights

To calculate the total number of streetlights, we can follow these steps:

1. Initial Number of Streetlights: 26 streetlights were initially installed. 2. Number of Streetlights that Went Out: Out of the 26 streetlights, 21 went out. 3. Additional Streetlights: 15 streetlights were added later.

Calculation

To find the total number of streetlights, we can use the following formula: Total number of streetlights = Initial number of streetlights - Number of streetlights that went out + Additional streetlights

Solution

Using the given information: Total number of streetlights = 26 - 21 + 15 Total number of streetlights = 20

So, the total number of streetlights is 20.
