Explanation:

Step1: Calculate discounted meal price

Original price: $\$40$, discount: $10\%$.
Discounted price = $40 \times (1 - 0.10) = 40 \times 0.90 = 36$

Step2: Calculate price with sales tax

Discounted price: $\$36$, tax rate: $7.5\%$.
Price with tax = $36 \times (1 + 0.075) = 36 \times 1.075 = 38.70$

Step3: Calculate tip amount

Tip rate: $18\%$ on discounted price $\$36$.
Tip = $36 \times 0.18 = 6.48$

Answer:

1. $\$36$
2. $\$38.70$
3. $\$6.48$
