When he goes out to eat, Austin always leaves a tip for his server that is equal to 15% of his bill. Let f = the amount of the bill. Which algebraic expression could be used to calculate Austin's total cost of eating out at any restaurant?
if \(f\) is the amount of the bill and he leaves a 15% tip then the total cost would be \[ \large C=f+f\cdot15\%=f\cdot(1+0.15)=1.15f \]
So f.15 would be the algebraic expression?
