IV. Solve the following critical thinking problem, showing all work to support the final answer. Include a few words with the work to explain your steps and thought process along the way.
Four radishes and 2 squash weigh the same as 7 cucumbers. Twelve radishes and 9 cucumbers weigh
the same as 4 squash. How many radishes weight the same as one squash?

b

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
