Chin paid $16.24 for 7 bags of flour that were on sale for 10% off. Each bag contained 2 pounds of flour. What was the regular price for 1 pound of flour?

Respuesta :

Answer:

The regular price for 1 pound of flour was $ 1.29

Step-by-step explanation:

Let's use the Direct Rule of Three for calculating the regular price for the 7 bags purchased by Chin for 10% off:

Price        Percentage

$ 16.24        90

   x              100

***************************

90 * x = 16.24 * 100

90x = 1,624

x = 1,624/90

x = 18.05

Now, let's calculate the price of each bag of flour, this way:

Price of each bag = 18.05/7

Price of each bag = $ 2.58 (rounding to the next cent)

Finally, we can calculate the regular price for 1 pound of flour:

Regular price for 1 pound of flour = 2.58/2

Regular price for 1 pound of flour = $ 1.29
