To calculate the salesperson's commission, we can set up a proportion using the price of the Nintendo Switch Bundle and the salesperson's commission rate.
Let's denote the salesperson's commission as "x".
We know that the price of the Nintendo Switch Bundle is $399.99 and the commission rate is 3.5%.
We can set up the following proportion:
3.5 / 100 = x / 399.99
To solve this proportion, we can cross-multiply:
3.5 * 399.99 = 100 * x
Simplifying the equation:
1399.965 = 100x
To find the value of "x" (the salesperson's commission), we divide both sides of the equation by 100:
x = 1399.965 / 100
x = 13.99965
Therefore, the salesperson earned a commission of $13.99965 (rounded to $14) for selling the Nintendo Switch Bundle to the little girl.
