I would say A is your answer since your trying to isolate P you would divide everything by (1+rt).
T=5w
T= total cost
W= weeks
It can't be W= because the question is asking for total cost in dollars, so two options are cancelled out.
Can't be t=5+w because it's 5 per week and if, let's say calculating dollars for 2 weeks, the answer would be t=5+2=7 and that wouldn't be right
