Kelly works at a restaurant. Today, a family of four sat at one of her tables. Each person ordered a value meal, which has a cost of $9.50, along with a drink
, which has a cost of $1.50. If the family
also left Kelly a tip of 15%, what was the total amount that they paid?

9.50+1.50 = 11

11*4 = 44

44/100*115= 50.6

T= $50.60

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
