The number of roses sold since Monday at a flower store can be modeled by the function N(d) = 6d + 25 and the price
per rose can be modeled by P(d) = 0.02d2 – 0.04d + 0.49,
where d is the number of days since Monday.
According to this model, what is the total amount of revenue
generated by the store's rose sales on Sunday? Round your
answer to the nearest cent.
