The distance to the meeting place is 1047 miles if his car gets 29 mpg how many gallons of gas will he need

36.1g

Step-by-step explanation:

29mi 1 g

1047mix

x=1047×1/29=36.1g

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

answer: 5100 just subtract
