Answer:
The sample size is 
Step-by-step explanation:
From the question we are told that
The margin of error is 
The standard deviation is 
From the question we are told the confidence level is 94% , hence the level of significance is
=> 
Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%20%5E2)
=> ![n = [\frac{1.881 } * 22 }{5} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B1.881%20%7D%20%2A%20%2022%20%7D%7B5%7D%20%5D%20%5E2)
=>
Monday through Friday is 5 days.
Multiply the cost of lunch by number of days:
3.25 x 5 = $16.25
Subtract the total he spent on lunch from what he started with for money:
20 - 16.25 = 3.75
He had $3.75 left.
Let y be your total price for buying juice at the farmers market. And x be the amount of juices you buy. If each juice cost 5 bucks then you multiply 5 by x(amount of juice) to get y(your total)
The answer is C
So how?
I multiplied 48*.19= 9.12 then subtracted that from 48 and got 38.88 which rounds to 39
C is the answer
I hope this helps! :D
