Therefore, it will take the boy 10 months to save $280 for the video game.

Bob initially had 30 minutes for TV. He watched a game for 7 minutes and lost for 9 minutes. To find out how much time he had left, we subtract the time he spent from the starting time. Therefore, Bob had 30 - 7 - 9 = 14 minutes left.

To find the number of gallons of gas needed to drive 273 miles, we divide the total distance by the car's mileage. In this case, the car gets 20 miles per gallon, so we divide 273 by 20. The result is approximately 13.65. Since we can't have a fraction of a gallon, we round up to the nearest whole number, which is 14. Therefore, you would need 14 full gallons of gas to drive 273 miles.
