Answer: Time taken by pipe C to empty the tank = 5 hours.
Step-by-step explanation:
Pipe A can fill a tank in 5 hours.
Let time taken by Pipe C = x ( hours)
Time taken by Pipe B = x-2 ( hours)

Answer:
50 cents
Step-by-step explanation:
The ratios can be added to find exactly how many of each coffees there are.
3 + 7 + 5 = 15
300 / 15 = 20
20 x 3 = 60 black coffees
20 x 7 = 140 sugared coffees
20 x 5 = 100 milk coffees
Multiply by the price.
60 x 50 = 3000 cents = $30 for black coffee
140 x 60 = 8400 cents = $84 for sugared coffee
100 x ? = 100? cents = $1? for milk coffee
Get rid of the ?.
164 - (30 + 84) = 50
$50 for milk coffee.
$1? = $50
? = $.50
