Answer 1

✅
`p + 63.43 + 87.15 + 81.96 = 311.62`

✅To take the lead, your score in the fourth round must be greater than 79.08.

Explanation:

If you score, 63.43, 87.15, 81.96 in the first, second and third round respectively, if the current leader has a total score of 311.62 points, the point p that you need to score to equal 311.62 points, can be found using the following equation:

`p + 63.43 + 87.15 + 81.96 = 311.62`

Solve for the value of p

`p + 232.54 = 311.62`

Subtract 232.54 from each side

`p = 311.62 - 232.54`

`p = 79.08`
