Answer:

1.80 + 3.72 (0.25 x b) = 13.02

Step-by-step explanation:

First, combine the "one-time" costs (the medium pendant and the medium chain)

1.80 + 3.72 = 5.52

Now, multiply the cost of the beads by the amount of beads you want

0.25 x 30 = 7.50

Now combine both costs to get the total cost

5.52 + 7.50 = 13.02

It would cost Tamara $13.02 to make a medium length necklace
