1. **Rent as a Percentage of Income**

Mia's income is $$9\,200$$ and her rent is $$1\,900$$. To find her rent as a percentage of her income, we use the formula:

$$
   \text{Percentage} = \left(\frac{\text{Rent}}{\text{Income}}\right) \times 100\%
   $$

Substituting the values:

$$
   \text{Percentage} = \left(\frac{1\,900}{9\,200}\right) \times 100\%
   $$

Simplify the fraction by dividing numerator and denominator by $$100$$:

$$
   \frac{1\,900}{9\,200} = \frac{19}{92}
   $$

Now, calculate the decimal value:

$$
   \frac{19}{92} \approx 0.2065
   $$

Multiply by $$100\%$$:

$$
   0.2065 \times 100\% \approx 20.65\%
   $$

Therefore, Mia's rent is approximately $$20.65\%$$ of her income.

2. **New Price after a $$15\%$$ Increase**

The original price of the bottle of water is $$R5.50$$. A $$15\%$$ increase means that we multiply the original price by $$1 + 0.15 = 1.15$$.

$$
   \text{New Price} = 5.50 \times 1.15
   $$

Multiply:

$$
   5.50 \times 1.15 = 6.325
   $$

Depending on rounding conventions (typically rounding to two decimal places for currency), the new price can be rounded to:

$$
   R6.33
   $$

Therefore, after a $$15\%$$ increase, the new price of the bottle of water will be approximately $$R6.33$$.
1. Mia's rent is approximately 20.65% of her income. 2. The new price of the bottle of water after a 15% increase is approximately R6.33.

2. Mia earns R9 200 a month. Her rent is R1 900 . Write her rent as a percentage of her income. 3. A bottle of Valpré water costs R5,50. If the price increases by \( 15 \% \), what will be the new price of the bottle?
