Question

At the start of the week, the amount of money in Howard's bank account varies directly with the number of hours he worked and inversely with the number of hours he spent shopping the past week. If has $2,000 in his bank account the week after spending 25 hours working and 4 hours shopping, how much does he have the week after spending 40 hours working and 1 hours shopping?
m = kh/s
2000 = k*25/4
k = 320, so

m = 320h/s
Now just plug in your work/shop hours to find m.
