When making a profit-maximizing "how much" decision, if the marginal benefit of a good or activity is greater than the marginal cost of that good or activity, then the individual can be made better off by: O changing the way marginal values are computed. increasing the amount of money spent on the good or activity until the marginal benefit of one more unit is less than the marginal cost. increasing the quantity as long as the marginal benefit of one more unit exceeds the marginal cost. O decreasing the quantity as long as the marginal benefit of one more unit exceeds the marginal cost
