Calculate the original price of each item using the formula: O r i g ina lP r i ce = 1 − 100 M a r k d o w n P erce n t a g e ​ F ina lP r i ce ​ .
Calculate the original prices for Chicken, Milk, Onions, Potato chips, Oranges, and Flour.
Sum the original prices of all items: 9.96 + 2.70 + 0.99 + 1.65 + 1.81 + 5.35 = 22.46 .
The total original price is approximately 22.46 ​ .

Explanation

Understanding the Problem We need to find the original prices of each item before the markdown and then sum them up to find the total original bill. The formula to find the original price is: O r i g ina lP r i ce = 1 − 100 M a r k d o w n P erce n t a g e ​ F ina lP r i ce ​ .

Calculating Original Prices Let's calculate the original price for each item:


Chicken: O r i g ina lP r i ce = 1 − 100 15 ​ 8.47 ​ = 0.85 8.47 ​ = 9.96470588
Milk: O r i g ina lP r i ce = 1 − 100 20 ​ 2.16 ​ = 0.80 2.16 ​ = 2.7
Onions: O r i g ina lP r i ce = 1 − 100 10 ​ 0.89 ​ = 0.90 0.89 ​ = 0.98888889
Potato chips: O r i g ina lP r i ce = 1 − 100 12 ​ 1.45 ​ = 0.88 1.45 ​ = 1.64772727
Oranges: O r i g ina lP r i ce = 1 − 100 25 ​ 1.36 ​ = 0.75 1.36 ​ = 1.81333333
Flour: O r i g ina lP r i ce = 1 − 100 18 ​ 4.39 ​ = 0.82 4.39 ​ = 5.35365854

Summing the Original Prices Now, let's add up all the original prices to find the total original bill:

T o t a l = 9.96470588 + 2.7 + 0.98888889 + 1.64772727 + 1.81333333 + 5.35365854 = 22.46831391
Rounding to two decimal places, the total original bill is approximately $22.47.

Final Answer The total of Jan's grocery bill if she purchased all of the items before they were marked down is approximately $22.47. Therefore, the closest answer is c. $22.46.

Examples
Understanding markdowns and original prices is very useful in everyday shopping. For example, if you see a shirt on sale for 30% off and it's listed at $28, you can calculate the original price to see if you're really getting a good deal. This skill helps you make informed purchasing decisions and manage your budget effectively. Knowing how to reverse a percentage discount is a practical tool for smart shopping.
