Asap offering 10 pointsraymond is buying boxes of party favors for his son's birthday party, he has to decide how many boxes he should purchase. a formula for this scenario is z = fc              n25 children will attend the birthday party. if each child gets 3 party favors and there are 15 favors in each box, how many boxes should raymond buy? z = number of boxesf = number of favors each child will getc = number of children at the partyn = number of party favors per box

The answer is:  " 5 boxes " .

Given the formula:
___________________________________________________________
                          →   "  " ; 

              in which:  
 
               Z = number of boxes ;  ← for which we shall solve ; 
 
               F = number of favors each child will get  = " 3 " {given} ; 

               C = number of children at the party =  " 25 " {given} ; 

               N = number of party favors per box =  " 15 " {given} ; 
___________________________________________________________
 
→  Plug these given values into the formula/equation ;

             to solve for:  " Z " ;  the number of boxes .  
___________________________________________________________

→    ;

       →   ;        

                      The "3" cancels to a "1" ; and the "15" cancels to "5" ; 

                  →  { since: " 3 ÷ 3 = 1 " ;  and since:  "15 ÷ 3 = 5 " } ; 
____________________________________________________________

→  And we can rewrite as:  
 
                    ;  

→  Note:  We change the:  "(1 * 25) "  (in the "numerator") ;  to:  " 25 " ; 

to simplify;  since:  "any value", multiplied by "1", results in that same value.

            →   As such:  "(1 * 25 = 25)" .
___________________________________________________________
 And we can rewrite our equation as:

            →  ;

And can further reduce; 
 
            →  to solve for our answer, "Z", the "number of boxes";  as follows:

            →    ; 

            →  [tex]Z =  " 5 "  .

            →  The answer is:  " 5 boxes " .
