Afew years ago. sarah acquired a parcel of land valued at $16,500. today, that same parcel of land has a value of $17.820. find the percent increase in the property's
value. round your answer to the nearest hundredth, if necessary.

8%

Step-by-step explanation:

Use formula

Old value = $16,500

New value = $17,820

Hence, the percent increase is

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
