Hey there :)
5 quarts of oil and an oil filter - $20.35
With couple - $4.43 less
Final cost?
We subtract 4.43 from $20.35
Why? That's the expected amount [ without a coupon ]
20.35
- 4.43
15.92
The final cost will be $15.92

Answer: 58/9
Step-by-step explanation:
Turn 6 into an improper fraction.

The speed of a boat in still water (b) is 50km/h. It takes the same time (t) for the boat to travel 10km (x) upstream as it does to travel 20km (y) downstream. Find the speed of the current.
upstream speed (u) = speed in still water (b) - stream speed (s) = b-s = 50-s
downstream speed (d) = speed in still water (b) + stream speed (s) = 50+s
time (t) = x/u = y/d
10/(50-s) = 20/(50+s)
10(50+s) = 20(50-s)
500 + 10s = 1000 - 20s
30s = 500
stream speed (s) = 500/30 = 16.6 km/h
