Isaac keeps track of the miles per gallon his car gets per week. He has accumulated the following data: (1, 24), (2, 24.48), (3, 24.97), (4, 25.47) What is the common difference or ratio? (1 point) Select one: a. The common difference is 0.48. b. The common difference is 0.50. c. The common ratio is 0.98. d. The common ratio is 1.02.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
