Explanation:
From the line diagram:
0 eggs takes 0 hours
1 egg takes 25 hours
let the number hours it take to get 3 eggs = x
1 egg = 25hrs
3 eggs = x
cross multiply:
x(1) = 3(25)
x = 75
Therefore, 3eggs will take 75 hours
let the number of eggs for 100 hours = y
1 egg = 25hrs
y = 100 hrs
cross multiply:
y(25) = 1(100)
25y = 100
y = 100/25
y = 4
Therefore in 100 hours, we would have 4 eggs
