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

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
