Your bill for dinner was $52. There is an 8% sales tax and you tip 20% of the original bill. How much does your dinner cost?

$66.56

Step-by-step explanation:

8% = 0.08

52 * 0.08 = 4.16

20% = 0.20

52*0.20 = 10.4

$52 + $4.16 + $10.4 = $66.56

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
