During a certain week, Jane worked j hours each day for 3 days, and Noah worked n hours each day for 5 days. Which expression represents the total combined number of hours worked that week by Jane and Noah?
A) 3j + 5n
B) 5j + 3n
C) 8jn
D) 15jn

The product of the number of hours that Jane worked per day ( j ) and the number of days worked (3) plus the product of the number of hours that Noah worked per day ( n ) and the number of days worked (5) must be equal to the total number of hours worked by both.

Mathematically speaking:

3j + 5n

During a certain week, Jane worked j hours each day for 3 days, and Noah worked n hours each day for 5 days. Which expression represents the total combined number of hours worked that week by Jane and Noah? A) 3j + 5n B) 5j + 3n C) 8jn D) 15jn
