To find the final cost of the meal after the discount and sales tax, we need to follow these steps: Calculate the discount by multiplying the cost of the meal by the discount rate (15%). Subtract the discount from the cost of the meal to find the final cost before the sales tax. Calculate the sales tax by multiplying the final cost before the sales tax by the sales tax rate (7%). Add the sales tax to the final cost before the sales tax to find the final cost of the meal. Step 1: Calculate the discount by multiplying the cost of the meal by the discount rate (15%). Discount = $20 * 15% = $3 Step 2: Subtract the discount from the cost of the meal to find the final cost before the sales tax. Final cost before tax = $20 - $3 = $17 Step 3: Calculate the sales tax by multiplying the final cost before the sales tax by the sales tax rate (7%). Sales tax = $17 * 7% = $1.19 Step 4: Add the sales tax to the final cost before the sales tax to find the final cost of the meal. Final cost = $17 + $1.19 = $18.19 This is the final cost of the meal. Lin's father pays $18.19 for the meal.
