Peyton borrowed some money from her friend in order to buy a new video game system and agreed to pay the friend back a constant amount each week. peyton originally borrowed $200 from her friend and after 4 weeks, she still owed her friend $100. write an equation for the function l(t),l(t), representing the amount peyton owes her friend after tt weeks.

Step-by-step explanation:

According to the problem, the initial condition is $200. If he owed $100 after 4 weeks, that means he paid $25 per week, so that would be the constant ratio. Therefore, the expression would be:

Where represents the amount owed, and represents weeks.

So, in the 4 week, that is, he owed:

As you can observe, the relation we found first perfectly to the problem. So, the final expression that model this problem is

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
