Cost of cooler alone = $ 7.47 Explanation: Method 1: Anton's bill including tax = $ 7.95 6 % of his bill accounts for sales tax. Sales tax = 6 100 × 7.95 ≈ $ 0.48 So cost of cooler alone = Total bill - tax = 7.95 − 0.48 = $ 7.47 Method 2: Anton's bill including tax = $ 7.95 , out of this 6 % is sales tax. This implies 94 % ( 100 − 6 ) of total bill accounts for cooler alone. Cost of cooler alone: = 94 100 × 7.95 = 0.94 × 7.95 = $ 7.47
