Question

Quizplus · Accepted Answer

First we find how much it costs her to make each necklace:
0.10 + 20 x 0.02 = 0.50
Then we multiply by the number of necklaces she makes:
0.50 x 33 = 16.5
Since we are dealing with money, which always uses two decimal places, we will just an a zero in the second decimal place.
$16.50
