12 weeks

Explanation:

Josiah and kiri are each saving money josiah starts with 100$ in savings accound and adds 5$ per week . Kiri with 40$ in her savings account adds 10$ each week after how weeks Josiah and kiri will have the same amount of money in their savings account

Josiah:

100 + 5w

Kiri:

40 + 10w

Where,

w = number of weeks

After how weeks Josiah and kiri will have the same amount of money in their savings account

Equate the savings of the both of them

100 + 5w = 40 + 10w

100 - 40 = 10w - 5w

60 = 5w

w = 60/5

= 12

w = 12 weeks

Josiah and kiri will have the same amount of money in their savings account after 12 weeks
