A company selling widgets has found that the number of items sold, x, depends upon the price, p at which30000they're sold, according the equation =(0.6p + 1)²Due to inflation and increasing health benefit costs, the company has been increasing the price by $0.03per month. Find the rate at which revenue is changing when the company is selling widgets at $3 each.Revenue is changing at a rate ofdollars per month.
