Answer:
The original price range of soda is $10 to $39.4
Step-by-step explanation:
Given as :
The discount coupon applied on grocery = 5%
The cost of soda after discount coupon ranges = $0.50 to $1.97
Let the original price range of soda = $A
Now, According to question
discount on original price = the cost after discount
So, initial original price = x
5% of x = $0.50
0.05 × x = $0.50
∴ x = 
i.e x = $10
Again final original price = y
5% of y = $1.97
0.05 × y = $1.97
∴ y = 
i.e y = $39.4
So, The original price range of soda = $A = $10 to $39.4
Hence, The original price range of soda is $10 to $39.4 Answer

Answer:
They could have asked more than 100 people or it just went over because of the percentages and they didn’t know
Step-by-step explanation:
Total dogs 88
Total poodle = 33
P(Poodle, then Poodle) = (33/88)(33/88) = 9/64
Answer: 9/64
Answer: 208.
Step-by-step explanation:
The formula to find the minimum sample size is given by :-
(1)
, where z* = critical z-value (two tailed).
= Standard deviation ( from prior study ) and E = Margin of error.
As per given , we have
Margin of error : E= 0.29
Confidence level = 85%
Significance level =
Using z-table , the critical value (two -tailed)=
As per previous study , Variance =
Now, the required minimum sample size = 
[Substitute the values in formula (1)]
[ Round to the next integer]
Hence, the minimum number of third graders that must be included in a sample = 208.
