A researcher gathered data to predict the number of new types of plants (y) that will be in a state park after x years. After making a scatter plot of the data, she determined the equation of a line of best t. The equation is shown below. y = 0:25x + 8 Based on the equation, what is the number of new types of plants that will be in the park after 24 years?

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
