Final answer:
To calculate the number of video games you can buy with $66 and a game that costs $20, divide $66 by $20. The result is 3 with a remainder of 6, which means you can buy 3 games and have $6 left over.
Step-by-step explanation:
To calculate the number of video games you can buy, divide the total amount of money you have by the cost of one game, including tax. In this case, you have $66 and the game costs $20 with tax.
So, you would divide $66 by $20 to find the number of games you can buy.
$66 ÷ $20 = 3 remainder 6.
After dividing, you get a quotient of 3 with a remainder of 6. This means you can buy 3 video games with $66 and still have $6 left over.
