Let's assume that the number of magazine subscriptions you sell in a week is "x".
Then, your earnings from selling magazine subscriptions would be:
130x dollars
Your base salary is $90.00 per week, so your total earnings would be:
Total earnings = 130x + 90
We want to find the value of "x" that makes the total earnings at least $1000.00 per week, so we can set up the following inequality:
130x + 90 ≥ 1000
Subtracting 90 from both sides, we get:
130x ≥ 910
Dividing both sides by 130, we get:
x ≥ 7
Therefore, you need to sell at least 7 magazine subscriptions per week to make at least $1000.00 per week.
