4.) Ariel makes her own jewelry to sell at the Street Fair. She can make 12 bracelets in 4 hours. If she works for 5 hours every Thursday for 4 Thursdays, how many bracelets will she make?

60bracelets

Step-by-step explanation:

To solve this problem, we need to find her rate. This is the number of jewelries she makes per unit of time;

         Rate  =

 Number of jewelries  = 12 bracelets

  time  = 4hrs

     Input the parameters:

           Rate  =   = 3bracelets/hr

She works 5hrs for 4 Thursdays;

   Number of hours worked  = 5 x 4 = 20hrs

Now, working at a rate of 3bracelets/hr for 20hrs, the number of bracelets she will produce is given as;

  Number of bracelets  = number of hours x rate

                                       = 20 x 3

                                       = 60bracelets
