a bus pass costs $5 per week. which of the following equations shows the total cost in dollars, t, of the bus pass for a certain number of weeks, w?
t = 5w
w = 5t
t = 5 + w
w = 5 + t

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 

False because how does that work?

Google it that might work
