Answer:

Step-by-step explanation:

Florence \ washed \ 3\  cars \  and\  earned\  = \$ x\\\\

Cost\ of \ washing \ one \ car = \frac{x}{3}

Anona \ washed \ 5 \ cars \ and \ earned \ 16 \ more \ than \ Florence = x + 16

Cost\ of \ washing \ one \ car \ by \ Anona = \frac{x +16}{5}

 \frac{x}{3} = \frac{x + 16}{5}\\                    [ \ cross \ multiply \ ]

5 \times x = 3 \times( x + 16)\\\\5x = 3x + 48\\\\5x - 3x = 48\\\\2x = 48\\\\x = 24

Cost \ of \ washing \ one \car = \frac{x}{3} = \frac{24}{3} = \$ 8

Therefore ,

                 Florence earned $24

                 Anona earned 24 + 16 = $40  

                 Caragh Washed 4 cars, so Caragh earned = 8 x 4 = $32

Find the optimal solution for the following problem. (Round your answers to 3 decimal places.)
irina1246 [14]

Answer:

Maximize C =9x + 7y

8x + 10y \leq 17

11x + 12y\leq 25

and x ≥ 0, y ≥ 0

Plot the lines on graph

8x + 10y \leq 17

11x + 12y\leq 25

x\geq 0

y\geq 0

So, boundary points of feasible region are (0,1.7) , (2.125,0) and (0,0)

Substitute the points in  Maximize C

At  (0,1.7)

Maximize C =9(0) + 7(1.7)

Maximize C =11.9

At  (2.125,0)

Maximize C =9(2.125) + 7(0)

Maximize C =19.125

At   (0,0)

Maximize C =9(0) + 7(0)

Maximize C =0

So, Maximum value is attained at   (2.125,0)

So, the optimal value of x is 2.125

The optimal value of y is 0

The maximum value of the objective function is 19.125
