Select the correct answer.
Eric has challenged himself to walk 24,000 steps in 4 days. If Eric walks the same number of steps each day, which function represents the
number of steps Eric still needs to walk to reach his goal with respect to the number of days since he started his challenge?
OA y = 8,000x - 24,000
OB. y = -8,000x + 24,000
OCy6,000x - 24,000
OD. y=-6,000x + 24,000

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

x=0
