Give the step-by-step reasoning process and then the final answer. Danielle wants to make her own popsicles. She finds out she needs popsicle sticks, molds, and juice. She has $10 for supplies. She buys one set of molds for $3 and a pack of 100 popsicle sticks for $1. Each bottle of juice makes 20 popsicles and costs $2. How many popsicle sticks will she be left with if she makes as many as she can?
She has $6 left after buying initial supplies because 10 - 3 - 1 = 6. She can buy 3 bottles of juice because 6 / 2 = 3. She can make 60 popsicles because 20 x 3 = 60. She has 40 sticks left because 100 - 6 60 = 40.
The final answer: 40.
