1. Problem 1: Joy's commission calculation. Joy receives an 8.5% commission on ₱55,000 booking total. 2. Convert the percentage to decimal: 8.5% = $$ \frac{8.5}{100} = 0.085 $$. 3. Calculate commission: $$ C = 55000 \times 0.085 = 4675 $$. 4. Therefore, Joy receives a commission of ₱4675. --- 5. Problem 2: Clarisse's total payment including VAT. Clarisse's order cost ₱855, and VAT is 12%. 6. Convert VAT to decimal: 12% = $$ \frac{12}{100} = 0.12 $$. 7. Calculate VAT amount: $$ \text{Tax} = 855 \times 0.12 = 102.6 $$. 8. Calculate total amount to pay: $$ 855 + 102.6 = 957.6 $$. 9. Therefore, Clarisse pays ₱957.6 in total.
