 6 ways

Step-by-step explanation:

Given : Bella is planning to write in a journal.

Some pages will have one journal entry on them, and other pages will have two journal entries on them.

Total required entries to make = 10

We can write 10 =10(1)+0

i.e. she can write one entry one journal entry on each page. → Way 1

10=8(1)+2(1)

i.e.  she can write one entry one journal entry per page for 8 pages and 2 journal entries on one page .→ Way 2

10=6+4 = 6(1)+2(2)

i.e.  she can write one entry one journal entry per page for 6 pages and 2 journal entries on 2 pages . → Way 3

10=4+6 = 4(1)+2(3)

i.e.  she can write one entry one journal entry per page for 4 pages and 2 journal entries on 3 pages .→ Way 4

10=2+8 = 2(1)+2(4)

i.e.  she can write one entry one journal entry per page for 2 pages and 2 journal entries on 4 pages .→ Way 5

10=0+10= 0+ 2(5)

i.e.  she can write 2 journal entries on 5 pages . → Way 6

Hence, the total number of ways she can write them in her journal = 6
