Answer: correct if wrong:)
4. 36 workers
Step-by-step explanation: 8-2=6
6x6=36
Number of days, y: 8
Number of workers, x: 6
Inverse Variation equation:
y = k/x
Find k, the constant of variation:
8 = k/6
k = (6)(8)
k = 48
Find the number of workers, x, if the number of days are reduced by 2.
(8-2) = 48/x
x = 48/6
x = 8 workers
ANSWER: 8 workers have to work if the same job is to be finished two days in advance or in 6 days.
