A factory makes around 5000$ mechanical toys every month, and the defects are removed by a quality control expert.

How many defects were there in January, February, and March combined?
There were 14$ defects in January, 15$ in February, and 19$ in March.

To find the total number of defects in January, February, and March combined, you add the number of defects in each month.

Total defects = January defects + February defects + March defects
Total defects = 14 + 15 + 19
Total defects = <<14+15+19=48>>48

Therefore, there were a total of 48 defects in January, February, and March combined.
