A) 3j + 5n

B) 5j + 3n

C) 8jn

D) 15jn

Answer: A) 3j + 5n

Step-by-step explanation:

Hi, to answer this question we have to write an expression using the information given:

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
