The stem-and-leaf plot below shows the number of kilometers walked by participants in a benefit walk. Number of Kilometers Walked by Participants 120 3 6 7 9 9 130 1 4 5 5 140 0 2 3 3 8 8 9 150 2 2 2 2 3 5 5 7 160 5 5 9 9 170 4 5 (Key: 12 | 3 means 12.3 km) How many of the walkers traveled more than 16 km? What is the furthest that someone walked?

Would you mind taking a screen shot of it?

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
