The score in the next game that will raise her average to 88 is 106.

To calculate the score in the next game, first, we need to calculate the number of games played by Janice.

Formula:

  • (85n+99)/(n+1) = 87............. Equation 1

Where:

  • n = number of games played by Janice.

Solve for n.

  • 85n+99 = 87(n+1)
  • 85n+99 = 87n+87

Collect like terms

  • 87n-85n = 99-87
  • 2n = 12
  • n = 12/2
  • n = 6.

For her average to raise to 88, she needs to score y.

  • [85(6)+y]/(6+1) = 88
  • (510+y)/7 = 88
  • y+510 = 616
  • y = 616-510
  • y = 106.

Hence, The score in the next game that will raise her average to 88 is 106.
