Step-by-step explanation:

$861.6

Step-by-step explanation:

Bodily injury: $310

Property damage: $175

Collision: $148

Comprehensive: $85

$310+$175+$148+$85 = $718

$718 x 1.2 = $861.6

The annual premium is $861.6

(took the test)

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
