anonymous · Answer

and how did you get this

texaschic101 · Answer

ok....let me explain
t = # of shirts
It costs $30 per shirt plus a one time fee of $2.75
so your equation would be : 30t + 2.75

and if t = 5 (for 5 tee shirts)
sub 5 in for t
30t + 2.75 = 
30(5) + 2.75 =
150 + 2.75 = 
152.75

so you have your equation and you have your total cost when you buy 5 tee shirts

any better understanding ?
