Question

at the beginning of the month, edwards used car dealership had 80 cars on the lot. since then, edward decreased the number of cars on the lot by 15%. how many cars are on the lot now?
enter the number of cars on the lot now.

Explanation:

Step1: Identify the original number of cars

The original number of cars on the lot is 80 (as inferred from the context: "At the beginning of the month, Edward's Used Car Dealership had 80 cars on the lot").

Step2: Determine the percentage decrease

The percentage decrease is 1%. To find the amount of decrease, we calculate \( 80\times\frac{1}{100}=0.8 \). But wait, maybe there's a typo or misread. Wait, the image shows "1" in the percent decrease? Wait, no, maybe the original problem (from the partial text) is: "At the beginning of the month, Edward's Used Car Dealership had 80 cars on the lot. Since then, Edward decreased the number of cars on the lot by 1%. How many cars are on the lot now?" Wait, no, the user's image has a box with 100? Wait, maybe the original number is 100? Wait, the text on the left: "Enter the number of cars on the lot now." The right side: "decrease", "Amount Decrease", "Amount Original". Wait, maybe the original number is 100, and the percentage decrease is 1%? Wait, no, let's re-express.

Wait, maybe the problem is: Original number of cars = 100, percentage decrease = 1%. Then the amount of decrease is \( 100\times 0.01 = 1 \). Then the number of cars now is \( 100 - 1 = 99 \). But that seems odd. Wait, maybe the original number is 80, and the percentage decrease is 1%? Wait, the image is unclear, but let's assume the original number is 100 (from the 100 in the box) and the percentage decrease is 1%.

Step1: Calculate the amount of decrease

If original number \( N = 100 \) and percentage decrease \( p = 1\% = 0.01 \), then amount of decrease \( D = N\times p = 100\times 0.01 = 1 \).

Step2: Calculate the current number of cars

Current number \( C = N - D = 100 - 1 = 99 \).

Wait, but maybe the original number is 80. Let's check the partial text: "At the beginning of the month, Edward's Used Car Dealership had 80 cars on the lot. Since then, Edward decreased the number of cars on the lot by 1%. How many cars are on the lot now?" Then:

Step1: Calculate the amount of decrease

\( D = 80\times 0.01 = 0.8 \). But we can't have 0.8 cars, so maybe the percentage is 10%? Wait, the image shows "1" in the percent box. Maybe the original number is 100. Let's proceed with original number 100, percentage decrease 1%.

Answer:

99 (If original is 100, 1% decrease: 100 - 1 = 99) or if original is 80, 80 - 0.8 = 79.2 (but cars are whole numbers, so maybe 100 is correct). Wait, the image has "100" below the input box, so original number is 100. Then current number is 99.
