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

Respuesta :

Convert the % numbers to decimals: 6.25% = 0.0625, 20% = 0.2
Now, the bill of $28.35 must add 6.25% of 28.35 for tax and 20% of 28.35 for tip.
So, to use an equation: Total cost = 28.35 + (28.35)(0.0625) + (28.35)(0.2) = 28.35 + 1.77 + 5.67 = $35.79.
