Answer:
The Inequality representing the number of sales needed is .
Mali need to make at least <u>17 sales</u> for to earn $100.
Step-by-step explanation:
Given:
Amount paid per week = $50
Amount paid on per sale = 3
Total amount to be earned $100
We need to write and solve the inequality to find the number of sales need to be make.
Solution:
Let the number of sales need to be make be 'x'.
Now we can say that;
Amount paid per week plus Amount paid on per sale multiplied by number of sales should be greater than or equal to Total amount to be earned.
framing in equation form we get;
Hence the Inequality representing the number of sales needed is .
On Solving above Inequality we get;
Subtracting both side by 50 using Subtraction property of Inequality we get;
Now Dividing both side by 3 Using Division property of Inequality we get;
Hence Mali need to make at least <u>17 sales</u> for to earn $100.
