A restaurant bill comes to $28.35 find the total coast if the tax is 6.25% and 20% tip is left on the amount before tax

Answer:The total cost  of the bill = $36.146Step-by-step explanation:Here, the total amount  of the bill = $28.35Now, the amount of tip = 20%So, calculating 20% on the bill amount, we get[tex]\frac{20}{100} \times 28.35  =  5.67[/tex]or, the amount of 20% tip = $5.67So, the total bill amount  after 20% tip = Bill Amount + Tip = $28.35 + $5.67 =  $34.02Now, the tax is calculated on the amount of  bill $34.02.[tex]\frac{6.25}{100} \times 34.02  =  2.126[/tex]or, the amount of tax on the bill = $2.126So, the total bill amount  after 6.25% tax  = Bill Amount + Tax =  $34.02 + $2.126 = $36.146Hence, the total cost  of the bill = $36.146.
