One landscaper works 1.5 times as fast as another landscaper. Find their individual times if it takes 9 hours working together to complete a certain job.

Landscaper #1 takes hours

Landscaper #2 takes hours

16.9 times 2.85

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

answer: 12,000
