Question
Emily subscribes to an online learning platform for $15 per month, which allows her to purchase courses at a discounted rate of $5 per course. The equation represents the total amount Emily spends each month on learning, where x represents the number of courses she buys. If Emily spent $60 in August on courses, then she purchased courses that month.

To find out how many courses Emily purchased in August, we can set up the equation based on her total spending on the learning platform.
Emily's spending consists of two components:
1. A monthly subscription fee of $15.
2. The cost of the courses purchased, which is $5 per course.
The total amount Emily spends in a month can be represented by the following equation:
\[
\text{Total Spending} = \text{Subscription Fee} + (\text{Cost per Course} \times \text{Number of Courses})
\]
Substituting the values we have:
\[
60 = 15 + 5x
\]
where \( x \) is the number of courses she buys.
To solve for \( x \), first, subtract the subscription fee from both sides:
\[
60 - 15 = 5x
\]
\[
45 = 5x
\]
Now, divide both sides by 5:
\[
x = \frac{45}{5} = 9
\]
Therefore, Emily purchased **9 courses** in August.
