Answer:
It will take 18 weeks
Step-by-step explanation:
Here, we are told that she owes a total of $81 which decreases at a rate of $4.50 per week
The number of weeks it will take to finish paying the debt will be the amount owed divided by the payment per week
Mathematically that is 81/4.5 = 18
Let us say that the number of weeks is "x" and the number of chores is "y".
If we state an algebraic expression for Janie's allowance it would be
3x+2y=13
However, there are two variables, hence many answers. To solve this problem, there must be more information about the relation between x and y.
