0. He spent $19.99 on a game and $8.21 on snacks. We need to find the percentage of money left with Kai.

2. Solution Steps

Step 1: Calculate the total amount spent.

Total spent = Cost of game + Cost of snacks

Total spent = $19.99 +$8.21 = $28.20$

Step 2: Calculate the amount of money left.

Money left = Initial amount - Total spent

Money left = $30 -$28.20 = $1.80$

Step 3: Calculate the percentage of money left.

Percentage left = (Money left / Initial amount) * 100

Percentage left = $(\frac{1.80}{30}) * 100$

Percentage left = $0.06 * 100$

Percentage left = $6$%

3. Final Answer

6%
