You can put this solution on YOUR website!
m, price for Marigold seeds
c, price for Carnation seeds

system%2820m%2B16c=278.72%2C23m%2B20c=329.44%29

system%285m%2B4c=69.68%2C23m%2B20c=329.44%29
Any method you want from here for this system. Suggestion is multiply all first equation by 5 and eliminate terms of c.
