Answer 1

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
