A workers wage w varies directly as the number of hours h wo

A worker\'s wage (w) varies directly as the number of hours (h) worked. If $90 is earned for working 8 h, how much is earned for working 30 h? w = $

Solution

worker\'s wage (w) varies directly as the number of hours (h) worked

equation becomes

w = k h

where , w = wage

h = hours

k = proportionality constant

therefore , If $90 is earned for working 8 h

90 = k (8)

k = 90 / 8 = 11/25

hence, wage earned by working 30 hours

w = 11.25 (30) = 337.5

w = $ 337.5
