Time taken to fill the bathtub is 8 min
time taken to drain the bathtub is 12 min
fraction of bathtub filled in 1 hour=1/8
fraction of bathtub drained in 1 hour=1/12
fraction that will be filled in a minute given that both taps are opened at he same time:
1/8-1/12
=1/24
thus time taken for the bathtub to be filled is 24 min

Step-by-step explanation:
If all orders are backlogged and the cost of lost customer goodwill from carrying a single chair on backorder is $20, what order-up-to (base stock) level should CITW use?
Company has mean demand = 1000
Standard deviation = 200 chairs
95% service level, Z=1.64 ⇒ 1000 - 1.64 * 200 = 1000 – 328 =672 chairs.
The order up to base model is 672 chairs.

4/52 = 1/13 ... there are four 5 cards in a deck and 52 cards in a standard deck so 4/52 !
Mason will have 6 left over Eric will have 3 left over.
Oliva= 9 +9 = 18 ( no left over)
Mason= 9+9=18+6 =24 ( 6 left over)
Nia= 9+9+9+9+9+9+9=63 (no left over)
Eric= 9+9+9+9+9+9+9+9=72+3=75 (3 left over)
