speed with no wind = s
speed with wind = s + 5
speed against wind = s - 5
time = t
speed = distance/time
distance = speed * time
With wind, time = t, speed = s + 5, distance = 50
50 = (s + 5)t
Against wind, time = t, speed = s - 5, distance = 30
30 = (s - 5)t
t = 30/(s - 5)
50 = (s + 5) * 30/(s - 5)
50(s - 5) = (s + 5) * 30
50s - 250 = 30s + 150
20s = 400
s = 20
Answer: 20 mph

The first 2 and last 2. I just did this assignment
First you would multiply $860 and .06 (6%) and you'll get $51.60 (which is your tax) Then, you'll add $860 and $51.60 to get $911.60. BUT she had that rebate. Finally, you will take $911.60 and subtract it by 85 (the rebate) and get $826.60
