Question

Jordan borrowed some money from his friend in order to help buy a new video game system and agreed to pay the friend back a constant amount each week. Jordan originally borrowed $120 from his friend and after 2 weeks, he still owed his friend $90. Write an equation for L, in terms of t, representing the amount Jordan owes his friend after t weeks.

Answer 1

To write an equation representing the amount Jordan owes his friend after t weeks, we need to determine the rate at which he pays his friend back each week. From the given information, we know that Jordan originally borrowed $120 and after 2 weeks, he still owed $90. Therefore, the equation representing the amount Jordan owes his friend after t weeks is L = 120 - 15t.

Step-by-step explanation:

To write an equation representing the amount Jordan owes his friend after t weeks, we need to determine the rate at which he pays his friend back each week. From the given information, we know that Jordan originally borrowed $120 and after 2 weeks, he still owed $90. This means that he paid back $120 - $90 = $30 in 2 weeks. To find the weekly payment rate, we divide the amount paid back by the number of weeks: $30 / 2 weeks = $15 per week.

Therefore, the equation representing the amount Jordan owes his friend after t weeks is:

L = 120 - 15t
