Shelley works as an Optican in Whitehorse White YT, her store is selling last year‘s glasses frames at a savings of 30%. What will you pay for frames that were originally priced at $149 if 5% GST is charged.

To determine the final price of the glasses frames, we'll follow these steps:

1. **Calculate the discount**: 
   The frames are on sale with a 30% discount. First, calculate how much 30% of $149 is:
   \[
   \text{Discount} = 149 \times 0.30 = 44.70
   \]
   
2. **Subtract the discount from the original price**: 
   To get the sale price of the frames:
   \[
   \text{Sale Price} = 149 - 44.70 = 104.30
   \]

3. **Add the 5% GST**:
   To calculate the GST, multiply the sale price by 5%:
   \[
   \text{GST} = 104.30 \times 0.05 = 5.215
   \]
   
4. **Add the GST to the sale price**:
   The final price, including GST, will be:
   \[
   \text{Final Price} = 104.30 + 5.215 = 109.515
   \]
   
5. **Round to the nearest cent**:
   The final price you will pay is **$109.52**.
