Answer:
Y(p) = (p / 5) * $20 - $150
Explanation:
Joey's business expenses can be represented by the initial advertising cost of $150. His earnings depend on the number of parrots he sells, which can be represented as $20 in profit for every 5 parrots sold. So, for every 5 parrots sold, he earns $20 in profit.
To determine how much money Joey's business has made after selling "p" parrots, you can use the following equation:
Total Earnings = Total Profit - Advertising Cost
Total Profit can be calculated based on the number of parrots sold, with each set of 5 parrots earning him $20 in profit. To express this in an equation, you can use:
Total Profit = (p / 5) * $20
So, the equation Joey can use to determine how much money his business has made after selling "p" parrots is:
Y(p) = (p / 5) * $20 - $150
Where:
Y(p) represents the total money his business has made after selling "p" parrots.
p is the number of parrots sold.
$20 represents the profit earned for every 5 parrots sold.
$150 is the initial advertising cost.
