Hi I really need help with this question please,
Mrrafil [7]

Answer:

{ ( \sqrt{30 - x} )}^{2}  =  {x}^{2}  \\ 30 - x =  {x}^{2}  \\  \\  {x}^{2}   +  x - 30 = 0 \\ delta = 1 - 4 \times ( - 30) \times 1 = 121 \\ x1 =  \frac{ - 1 +  \sqrt{121} }{2 \times 1}  =  \frac{ - 1 + 11}{2}  = 5 \\ x2 =  \frac{ - 1  -   \sqrt{121} }{2 \times 1}  =  \frac{ - 1  -  11}{2}  =  - 6 \\

Help please mathematics 22 -24
Pavel [41]

Answer:  (22) $9,075     (23) $656.25      (24) $217.13

<u>Step-by-step explanation:</u>

Cost Function: C(x) = 5.75x + 8,000

              C(10,000) = 5.75(10,000) + 8,000

                                = 57,500     + 8,000

                                = 65,500

Revenue Function: R(x) = 9.50x

                        R(7,850) = 9.50(7,850)

                                       =    74,575

Profit Function: P(x) = R(x) - C(x)

                                 = 74,575 - 65,500

                                 = 9,075

*****************************************************************************

Retail = Unit Cost + Unit Cost × Markup

         =     $375    +         $375 × .75

         =     $375    +           $281.25

         =     $656.25

*****************************************************************************

$225 but if paid within 10 days there is a 3.5% discount

Discount = $225 - $225 × .035

               =  $225 -     $7.88

               =  $217.13
