Answer:
Vanessa´s total pay was $482.50.
Explanation:
We have to add the amount of the 5% commission on Vanessa´s sales to her base salary of $400 to find out her total pay.
Since the total value of her sales was $1650, the amount (x) of her commission will be:
x = 1650 × 
 
 
x = 16.5 × 5 
x = 82.50 
Adding this to her base salary we get: 
400 + 82.5 = 482.5
