Final answer:
b. $448.50. Jenn will make $448.50 if she sells 3/5 of her merchandise.
Step-by-step explanation:
To find out how much money Jenn will make if she sells 3/5 of her merchandise, we need to find out the number of bracelets and necklaces she will sell. If Jenn has 50 bracelets, 3/5 of her bracelets would be (3/5) x 50 = 30 bracelets. Similarly, if Jenn has 60 necklaces, 3/5 of her necklaces would be (3/5) x 60 = 36 necklaces.
Next, we need to find out the total amount of money she will make by selling these items. Jenn sells each bracelet for $3.75, so the total money she makes from selling bracelets would be 30 x $3.75 = $112.50. Similarly, Jenn sells each necklace for $8.50, so the total money she makes from selling necklaces would be 36 x $8.50 = $306.
Finally, to find out the total money Jenn will make, we add the money from selling bracelets and necklaces, which gives us $112.50 + $306 = $418.50. Therefore, the correct answer is option b. $448.50.
