Best ResponseYou've already chosen the best response.0After some sleep, I see where I went wrong :) b=6 is good, but when I used it down here I made it "+6".....which of course threw off my numbers.... (2,18) (4,66) (10,450) a = (6618) (42)(6) < right there    (164) (164) a = 48 12 60    =  = 5 12 12 12 a = 5; b = 6 ; now THOSE are the right numers :)

Best ResponseYou've already chosen the best response.0c = 18 4(a)  2(b) c = 18  4(5)  2(6) c = 18 20 +12 c = 30  20 c = 10 y = 5x^2 6x +10 is the good equations. y = 5(8)^2 6(8) +10 y = 5(64) 48 +10 y = 320 38 y = 282 the cost of 8 calculator costs $282
