Question

A worker's wage (w) varies directly as the number of hours (h) worked. If $114 is earned for working 8 h, how much is earned for working 30 h?

Answer 1

Worker earned `$427.50` for working `30` hours.

Explanation:

Wage(w) varies directly as the number of hours(h).

So `w oo h or w= k*h :. k = w/h = 114/8 =14.25`. Where k is constant of variation.

Now `h=30 ; w=? ; w=k*h=14.25*30=427.50`

He earned `$427.50` for working `30` hours.[Ans]
