Then x = 3 times 5 = 15.
12 is 3 times y, so y = 4.
We are asked in the problem to determine the number of quarters that are needed to complete 4975 units given the equation y = x6 − 25x4 + 199x2 where y is the number of manufactured units and x is the number of quarters needed.
substituting y = 4975, we find x. <span>x is readily found using calculator.</span>
