Justin bought some chocolate, 3 lollipops, and some bubble gum at the candy store.  Pieces of chocolate cost $0.15 each, lollipops cost $0.25 each, and pieces of bubble gum cost $0.50 each.  If c represents the number of chocolate pieces he bought, and g represents the number of pieces of bubble gum he bought, which expression represents the amount of money Justin spent at the candy store?



To represent the total amount of money Justin spent at the candy store, we need to sum the cost of each type of candy he bought.

1. **Chocolate**: Each piece costs $0.15, and he bought $ c $ pieces. The total cost of the chocolate is:
   \[
   0.15c
   \]

2. **Lollipops**: Each lollipop costs $0.25, and he bought 3 lollipops. The total cost of the lollipops is:
   \[
   0.25 \times 3 = 0.75
   \]

3. **Bubble Gum**: Each piece costs $0.50, and he bought $ g $ pieces. The total cost of the bubble gum is:
   \[
   0.50g
   \]

Now, sum up all these amounts to get the total cost:

\[
0.15c + 0.75 + 0.50g
\]

This expression represents the total amount of money Justin spent at the candy store.
