Percentage of tip that needs to be given for hair cut = 15% Amount of tip is calculated without sales tax. Amount taken for the hair cut = 20 Amount of sales tax taken = 4.75 Then Amount of tip given = (15/100) * 20 = 300/100 = 3 So the total amount required for the hair cut = 20 + 4.75 + 3 = 27.75 So 25 is insufficient amount to cover the hair cut cost with tip and sales tax. The actual amount required to cover the total cost is 27.75<span />
