What is the total cost to conduct a market research survey with a $500 base fee plus $3 per question and $1.25 per person surveyed? the survey has 12 questions and will be sent to 300 people.

$911

Step-by-step explanation:

The initial base fee is $500 and will be added to the total cost to conduct the survey.

If each question is $3 then 12 questions will cost $36

If it costs $1.25 per person surveyed then for 300 people surveyed it would cost $375.

For 300 people doing 12 questions each:

=375 + 36 = $411

Total cost to conduct the survey = $411+$500= $911

answer: 59

step-by-step explanation:

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
