The ideal weight of a nickel is .17637 ounce. a bank teller weighs a roll of nickles to ensure there are 40 in the roll. write an inequality that best describes the allowance for an margin of error of .015 of an ounce in the total weight (w) of the roll. the weight of the wrapper is not part of the problem.
