The Campbell family is going camping. The base camping fee for each person and is $8.50 for the first night and $4.50 for each naught after that .How much will their family of 4 pay altogether to camp for 4 nights ?

$52

Step-by-step explanation:

First you would add up $8.50 + $4.50 which is the amount per night, or 13. Then you would multiply that by 4 to get 52.

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

mark has $52

hope this !
