Agrocer prepares free samples of a salad to give out during the day. by lunchtime, the grocer has given out 5 fewer than half the total number of samples. how many samples did the grocer prepare if she gives out 50 samples before lunch?

The grocer prepared total 110 samples.

Explanation

Suppose, the total number of samples the grocer prepared is  

By lunchtime, the grocer has given out 5 fewer than half the total number of samples. So, the number of samples given out by lunchtime

Now, it is given that she gives out 50 samples before lunch. That means...

So, the total number of samples the grocer prepared is 110.

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
