Step-by-step explanation:
If there is 1500 cellular phones per 1000 people, then the number of phones per person is:

Now we know that 
What are the numbers that are supposed to be plugged in?
Given that the point B is (1,1) is rotate 90° counterclockwise around the origin.
We need to determine the coordinates of the resulting point B'.
<u>Coordinates of the point B':</u>
The general rule to rotate the point 90° counterclockwise around the origin is given by

The new coordinate can be determined by interchanging the coordinates of x and y and changing the sign of y.
Now, we shall determine the coordinates of the point B' by substituting (1,1) in the general rule.
Thus, we have;
Coordinates of B' = 
Thus, the coordinates of the resulting point B' is (-1,1)
Answer:
Unit price of strawberries at Grocery Mart is $ 1.495 or 150 pennies
Unit price of strawberries at Baldwin Hills Market is $ 1.33 or 133 pennies.
Step-by-step explanation:
1 dollar = 100 pennies
Given:
Cost of 2 pounds of strawberries at Grocery Mart = $ 2.99
Cost of 3 pounds of strawberries at Baldwin Hills Market = $3.99
∵ Cost of 2 pounds of strawberries at Grocery Mart = $ 2.99
∴ Cost of 1 pound of strawberries at Grocery Mart = 
∵ Cost of 3 pounds of strawberries at Baldwin Hills Market = $3.99
Cost of 1 pound of strawberries at Baldwin Hills Market = 
Therefore, the unit price of strawberries at each grocery store is the cost of 1 pound of strawberries. So, unit rate at Grocery Mart is 150 pennies and at Baldwin Hills Market is 133 pennies.
