There are a few missing information that are pertinent to this problem.

Grade:                                                3         4         5
Number of science fair projects: 462    759     891

Total number of projects: 462 + 759 + 891 = 2112

99 long tables * 7 projects = 693 projects

2112 - 693 = 1419 projects

1419 projects ÷ 4 projects/short table = 354.75 tables or 355 short tables needed.

total projects: 2112
projects on long table: 693
projects on short table: 1419

The science fair judges will be science teachers and volunteers. Each judge will only have time to view 5 science fair projects. there are 133 science teachers. What is the fewest number of volunteers needed to have enough judges for all projects?

133 (number of teachers)

5 (project per teacher)

133×5=665

290+665=955
