Answer:
Inga must sell more than $14,375 per week in order to earn more in commision.
Step-by-step explanation:
Her sallary per week can be given in two ways:
sallary = 575
sallary = (4/100)*(sales per week)
If she wants to gain more from comissions than from the fixed sallary, then we can write an inequality such that:
(4/100)*(sales per week) > 575
sales per week > 575/(4/100)
sales per week > 575*(100/4)
sales per week > 57500/4
sales per week > 14375
Inga must sell more than $14,375 per week in order to earn more in commision.
