At a certain factory, 10 percent of the staplers produced on monday were defective and 2 percent of the nondefective staplers were rejected by mistake. if 90 of the nondefective staplers were rejected, what was the number of staplers produced that day?

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
