Best ResponseYou've already chosen the best response.0\[a x^2+b x+c=\text{cost} \]where x is the number of calculators produced. Plugging in the data point values for each of the cost/volume experience, yields three equations in three unknowns: {9 a + 3 b + c = 37, 49 a + 7 b + c = 213, 144 a + 12 b + c = 658} Solving the above for a, b and c and plugging in those values in the cost equation gives: \[5 x^26 x+10=\text{cost} \]At x = 8, the cost from the cost equation is 282
