1. **State the problem:** Calculate the total monthly pay for a salesperson at Xara showroom who has a base salary of 3800 plus a commission of 3.6% on sales up to 80000 and 7.2% on sales above 80000. The expected sales are 95000. 2. **Formula and rules:** Total pay = Base salary + Commission on first 80000 + Commission on sales above 80000 Commission on first 80000 = 3.6% of 80000 = 0.036 \times 80000 Commission on sales above 80000 = 7.2% of (Total sales - 80000) = 0.072 \times (Total sales - 80000) 3. **Calculate commissions:** Commission on first 80000 = 0.036 \times 80000 = 2880 Commission on sales above 80000 = 0.072 \times (95000 - 80000) = 0.072 \times 15000 = 1080 4. **Calculate total pay:** Total pay = 3800 + 2880 + 1080 = 7760 5. **Explanation:** The salesperson earns a fixed salary of 3800 plus commissions based on sales. The commission rate increases for sales above 80000, so we calculate commissions in two parts and add them to the base salary to find the total pay. **Final answer:** The total pay for a salesperson who sold 95000 is $7760.
