Inga can earn $575 per week in a plant store, or
she can earn 4% of total sales. How much would
Inga have to sell to earn more in commission than
in salary?

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.

the answer to the question is a  

it has the same slope and the same y-intercept.
