im not sure where to go from here. can someone help me? IM IN DESPERATE NEED


Central Perk Coffee Shop sells a specialty drink at $2.60 per cup. The shop sells about 200 cups per day. Customer surveys show that for every $0.05 decrease in price, the shop will sell 10 more cups per day. At what coffee price(s) will they earn a profit of $630?


Okay so I found the vertex which is (16, 648) but I'm not sure where I should input 630 to receive the coffee prices.

Thank you!! I really appreciate your help. I wanted to use the quadratic formula to get my answer. But, you got -200(P - 1.8)^2+ 648 = 630. I got -0.5(x-16)^2 + 648 = 630. Where did you get the 1.8?
