Answer:
The number of hardback books in book sale = 58
Step-by-step explanation:
Let the number of hardback books = m
So, the number of paperback books = 3 ( number of Hardbacks) - 12
= 3 m - 12
⇒the number of paperback books = 3 m -12
Now, total number of paperback books = 162
⇒ (3m -12) = 162
or, 3m = 162 + 12
or, 3m = 174 ⇒ m = 174 / 3
or, m = 58
Hence, the number of hardback books = 58

12T= =180 then divide both sides by 12
T= 15 hours
