Answer: The sales tax is $2,762.50 and total cost of the car including tax is $45262.50
Step-by-step explanation: The price of a new car is $42,500.
Sale tax rate = 6.5%
Sales tax on the car = 6.5% × 42,500
= × 42,500
= 0.065 × 42,500
= $2,762.50
Total cost of the car = 42,500 + 2,762.50 = $45262.50
The sales tax is $2,762.50 and total cost of the car including tax is $45262.50
