Answer:
To find the value of d, the number of tourists per day in July 2021, we can set up an equation based on the given information.
Let's start by determining the difference in the number of tourists per day in July 2021, which is the unknown value we are trying to find. We can express this difference as 10 times d.
Step-by-step explanation:
The equation can be written as:
30,000 = 10 * (d - 500)
Here, we subtract 500 from d since the problem states that the difference is 500, not the actual value of d itself.
To solve the equation, we'll isolate d by dividing both sides of the equation by 10:
30,000/10 = d - 500
3,000 = d - 500
Next, we'll solve for d by adding 500 to both sides of the equation:
3,000 + 500 = d
3,500 = d
Therefore, the number of tourists per day in July 2021, represented by d, is 3,500.
