(a) To find the amount of service charge Kayson has to pay, we calculate $$ 10 \% $$ of the cost of the spaghetti.

$$ \text{Service charge} = \frac{10}{100} \times 30 $$

$$ \text{Service charge} = 0.10 \times 30 $$

$$ \text{Service charge} = 3 $$

So, Kayson has to pay a service charge of $$ \$3 $$.

(b) To find out how much money Kayson pays for the meal, we need to add the service charge and the GST to the original cost of the spaghetti.

First, let's calculate the GST:

$$ \text{GST} = \frac{9}{100} \times 30 $$

$$ \text{GST} = 0.09 \times 30 $$

$$ \text{GST} = 2.7 $$

Now, we add the service charge and the GST to the original cost:

$$ \text{Total amount} = \text{Original cost} + \text{Service charge} + \text{GST} $$

$$ \text{Total amount} = 30 + 3 + 2.7 $$

$$ \text{Total amount} = 35.7 $$

So, Kayson pays a total of $$ \$35.7 $$ for the meal.
(a) Kayson pays a service charge of $$ \$3 $$. (b) He pays a total of $$ \$35.7 $$ for the meal.
