Answer:
60bracelets
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
