Determine each missing number. a) 25% of 84 = ■

b) 24% of 200 = ■

c) 10% of ■ = 5

Fil in the squares please!!

Step-by-step explanation:

a. 25% of 84  = ?

         To solve this problem;

          x 84

    25 goes in 100,  4 times

 = x 84

 = 21

b. x 200  = ?

    100 goes in 200 , 2 times

    24 x 2  = 48

c. of t  = 5

          x  t = 5

           = 5

           t  = 50

the correct answer is 1: 2

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
