Question
A store discounted the price of Doritos $0.35 and then a man bought 5 bags. If he paid a total of $12.70 for the bags of chips, how much was each bag originally?
Hint:
○ Form the equation using the given information.
○ Take variable quantity as x.
○ After discount the purchasing price will be
(original price - discount)
The correct answer is: $2.89
○ Given:
Discount on 1 pack of Doritos = $.0.35.
Total pack brought = 5.
Total money paid = $12.70.
○ Step 1:
○ Total discount;
Discount on 1 pack of Doritos= $.0.35
So,
Discount on 5 pack of Doritos= $.0.35 
5 = $ 1.75
○ Step 2:
○ Original price of 5 bags Doritos:
It is given that price of 5 bags after discount is $12.70
So, original price of 5 bags = 12.70 + 1.75 = 14.45
○ Step 3:
○ Original price of 1 bag:
original price of 5 bags = $ 14.45
original price of 1 bags = $ 
= 2.89
- Final Answer:
Hence, the original price of one bag of Doritos is $2.89.
