You and some friends went out to T.G.I.Fridays for dinner. You ordered a root beer, sweet potato fries and cheese quesadillas. The total bill came to $21.86. Your dad as told you many times that it's important to leave a good tip; about 20%. You have $27.00 in your wallet. Can you leave a 20% tip? How much would the total be if you left a 15% tip? Can you cover the cost?

Respuesta :

$27 - $21.86 = $5.14 

20% of $27 is  $5.40 
 No, you cannot cover the cost of this. 

15% of $27 is $4.05

You'd be able to afford to cover the cost with this with $1.09 left over.
