katen-ka-za [31]

Answer: R204.06

Step-by-step explanation:

Cost of clock = R179

Value Added Tax = 14%

The price of the clock will be the addition of the cost of the clock and the value added tax. This will be:

= R179 + (14% × R179)

= R179 + (0.14 × R179)

= R179 + R25.06

= R204.06

Therefore, the price of the clock is R204.06.
