Answer 1

The answer is D

17% of 13 is 2.21

13 + 2.21 = 15.21

Answer 2

Answer:

Option D

Step-by-step explanation:

Joseph's lunch costs = $13 without taxes

He leaves tip for the waiter = 17% of cost of the lunch

= 17% of $13

= 13 × $\frac{17}{100}$

= ( 13 × 0.17)

= $2.21

Total cost of lunch + tip = 13 + 2.21

                                       = $15.21

Option D is the answer.
