Question

Eva has $10 for lunch. Her meal cost $8.60. She wants to leave a 20% tip. Does she have enough money? Explain your reasoning.

Answer 1

No she doesn't have enough money. All you do is multiply 8.60 by .2 which come out to 1.72 and 8.60 plus 1.73 which equals 10.33 so she needs 33 more cents tone able to tip 20%.
