Answer:
16.7 sales
Explanation:
As a salesperson, you are paid $50 per day plus $3 per sale. This week you make $400. Define your variables then, write and solve an equation for the number of sales you made.
Let the number of sales be represented by x
As a salesperson, you are paid $50 per day plus $3 per sale. This week you make $400.
The number of days in a working week = 5
Hence:
Total Amount made(A) = $400
Hence
$50 × 7 + $3 × x = $400
350 + 3x = 400
3x = 400 - 350
3x = 50
3x = 50
x = 50/3
x = 16.7 sales
Therefore, the number of sales you made = 16.7 sales
