Answer:
Sale price of frames before gst = $160.30
Explanation:
Since we want to know the sale price given the original price and the discount rate, we can use the formula S = O - (rO) to help us, where:
- S is the sale price,
- O is the original price,
- and r is the discount rate as a decimal.
Thus, we can solve for S by substituting 229 for O and 0.30 for D in the formula above:
S = 229 - (0.30 * 229)
S = 229 - 68.7
S = 160.3
Therefore, the sale price of the frames before gst is $160.30.
