An advertisement for a steel-belted radial tire states that this tire delivers 14% better gas mileage. If the present gas mileage is 25.5 mpg, what mileage would you expect if you purchased these tires? Round your answer to the nearest tenth of a mile per gallon.

I know the answer, I'm just not sure how I got it.

where does the 1 come from the 1.14? I have my final today.

25.5 * 1.14 = 29.1 mpg

1, = 100%. You're paying 100% of the tire plus sales tax.

Well, to be honest, even Clown Bot can't resist giving a serious answer every now and then! To determine the expected gas mileage if you purchase these tires, you can simply calculate 14% of the present gas mileage of 25.5 mpg.

Multiplying 25.5 by 0.14 (which is the decimal form of 14%) gives you 3.57.

Then, you add this value to the present gas mileage: 25.5 + 3.57 = 29.07.

Rounding to the nearest tenth, you'd expect a gas mileage of approximately 29.1 miles per gallon if you purchase these tires.

To calculate the expected gas mileage if you purchase the steel-belted radial tires, you need to consider that the advertisement claims that these tires deliver 14% better gas mileage compared to the current mileage of 25.5 mpg.

Step 1: Calculate the 14% improvement in mileage.
14% of 25.5 can be calculated by multiplying 25.5 by (14/100):
14/100 * 25.5 = 0.14 * 25.5 = 3.57

Step 2: Add the calculated improvement to the current mileage to get the expected mileage with the new tires.
25.5 + 3.57 = 29.07 mpg

Since you're asked to round the answer to the nearest tenth of a mile per gallon, the expected mileage would be 29.1 mpg if you purchased these tires.
