There are 96.1% gas left after a game that had 23 hits on the ball

How to determine the amount of gas left?

After 10 hits, the amount of gas that escapes is:

Gas =1.7%

This means that the amount of gas that escape per hit is:

Rate =1.7%/10

Evaluate

Rate =0.17%

For 23 hits, the amount of gas that escapes would be:

Gas = 0.17% * 23

Evaluate the product

Gas = 3.91%

The amount of gas left is then calculated as:

Gas left = 100% - Gas escaped

This gives

Gas left = 100% - 3.9%

Evaluate

Gas left = 96.1%

Hence, there are 96.1% gas left after a game that had 23 hits on the ball
