The total number of pages written by Carla after 10 months is 170.
Here, we are given that Carla has already written 20 pages of a novel.
Further, she plans to write 15 pages per month.
Now, the number of pages she writes in 10 months will be given as-
15 × 10 = 150 pages
Thus, in 10 months time she will finish writing 150 pages.
However, she had already finished writing 20 pages earlier. These 20 pages will be added to the pages she writes in these 10 months to get the total number of pages written after 10 months.
Thus,
150 + 20
= 170 pages
Hence, we find that the total number of pages written by Carla after 10 months is 170.
