A restaurant bill comes to $28.35. Find the total cost if the tax is 6.25% and a 20% tip is left on the amount before tax.

Calculate the tip:
Tip = Bill Before Tax * Tip %
Tip = $28.35 * 20%
Tip = $5.67

Calculate Tax:
Tax = Bill without Tip * Tax %
Tax = $28.35 * 6.25%
Tax = $1.77

Total Cost = Bill + Tax + Tip
Total Cost = $28.35 + $5.67 + $1.77
Total Cost = $35.79
