Answer:
15 + 1.2x = 2.4x
13 pages
Step-by-step explanation:
Let x be the number of pages he needs to create,
∵ In the original programm the time taken by him in each page = 2.4 hours,
So, the total original time = 2.4x
Now, In the new program,
The learning time = 15 hours,
While the time per each page = = 1.2 hours,
Thus, the total new time to create x pages = 15 + 1.2x
According to the question,
15 + 1.2x = 2.4x
Which is the required equation,
Subtract 15 on both sides,
1.2x = 2.4x - 15
Subtract both sides by 2.4x
-1.2x = - 15
x = 12.5 ≈ 13
Hence, he needs to create 13 pages.
