A buss pass is set up with an initial balance of $80, and $2 is removed from the pass for each bus trip. Write an equation whose solution is the balance left on the bus pass, b, after taking 16 trips

Answer 1

Hi Ana,

b= bus pass balance

n= number of trips taken

b=80 -2*n so when n=0 b=$80 and when n=16 b=80-32=$48
