Question

You and some friends went out to T.G.I. Friday's for dinner. You ordered a root bear,sweet potato fries, and cheese quesadillas. The total bill came to $21.86. Your dad has told you many times that it's important to leave a good tip; about 20%. You have $26.00 in your wallet. How much would the total be if you left a 20% tip? Can you cover the cost?

Answer 1

21.86(1+20)/100≤26

21.86(120/100)≤26

21.86(1.2)≤26

26.232≤26

Since 26.232>26, you cannot cover the cost.

Answer 2

21.86 + 0.2(21.86) = 21.86 + 4.37 = 26.23 <== total with 20% tip

if u have $ 26, then u will not be able to leave a 20% tip....u would be short by 23 cents
