Answer:
Vanessa's total pay last week was $482.5
Step-by-step explanation:
She receives a constant quantity every week which is 400 dollars, that quantity will not variate in this process, but she has a variable in her payment every week that is determined by the sells she makes, this week she sold $1650 and she will receive 5% out of this, then 1650 x 0.05 = 82.5, this is the extra money she will receive giving a total of 400 + 82.5 = 482.5 dollars
