Final answer:
The equation to find the price of each avocado, denoted as p, is 6p = $9.60. By dividing both sides by 6, we find that p = $1.60, which represents the price of each avocado.
Step-by-step explanation:
To find the price p of each avocado, you can set up an equation that represents the total transaction. Brent paid with a $20.00 bill and received $10.40 in change. The amount spent on avocados is therefore $20.00 - $10.40 = $9.60. Since he bought 6 avocados, the price per avocado multiplied by the number of avocados should equal the total amount spent on them.
The equation to find the price p of each avocado is:
6p = $9.60
To solve for p, you would divide both sides of the equation by 6:
p = $9.60 / 6
p = $1.60
So the price p of each avocado is $1.60.
