On friday, you raked leaves for 4 neighbors, on saturay you raked leaves for 5 neighbors, and on sunday you raked leaves for 3 neighbors. over the three days you earned a total of $135. if you were paid the same amount at each house.

The amount paid by each house is $11.25

Step-by-step explanation:

Let the amount paid by each house is $K

Number of neighbors you worked for on Friday = 4

So the amount paid by all of them = 4K

Number of neighbors you worked for on Saturday = 5,

similarly amount paid = 5K

Number of neighbors you worked for on Sunday = 3,

here amount paid = 3K

Also, in total the amount paid = $135

So, Amount paid on {Friday + Saturday +Sunday} = Total Amount

or, 5K + 4K + 3K = $135

or, 12K = 135

⇒K =135/12 = $11.25

So, the amount paid by each house is $11.25
