The science fair project s are set up on tables. There are 99 long tables used. Each long table holds 7 projects. The rest of the projects are set up on short tables. Each short table can hold 4projects. What is the fewest number of short tables that will be needed for the rest of projects
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
Answer:
396
Step-by-step explanation:
Part 2 of question:
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
