A factory makes around 5000$ mechanical toys every month, and the defects are removed by a quality control expert.
There were 14$ defects in January, 15$ in February, and 19$ in March.
To find the total revenue generated by the factory each month, we need to subtract the defects' cost from the total revenue.
Total revenue in January = $5000
Defects cost in January = $14
Revenue after defects in January = $5000 - $14 = $4986
Total revenue in February = $5000
Defects cost in February = $15
Revenue after defects in February = $5000 - $15 = $4985
Total revenue in March = $5000
Defects cost in March = $19
Revenue after defects in March = $5000 - $19 = $4981
So, the revenue after removing defects in January, February, and March is $4986, $4985, and $4981, respectively.
