Questions: Teresa bought 3 boxes of chocolate. Each box has 9 pieces of chocolate inside. Teresa gave away 15 pieces of chocolate. How many pieces of chocolate does she have left?

Solution Steps

1. Calculate the total number of chocolates Teresa initially had by multiplying the number of boxes by the number of pieces per box.
2. Subtract the number of chocolates Teresa gave away from the total number of chocolates she initially had to find out how many pieces she has left.

The total number of chocolates Teresa initially had can be calculated as follows: \[ \text{Total Chocolates} = \text{Boxes} \times \text{Pieces per Box} = 3 \times 9 = 27 \]

Next, we subtract the number of chocolates Teresa gave away from the total chocolates: \[ \text{Chocolates Left} = \text{Total Chocolates} - \text{Chocolates Given Away} = 27 - 15 = 12 \]
