a salesperson earns $175 per week plus a commission equal to 4% of her sales. This week her goal is to earn no less than $525.
Let x be the amount of sales in dollars
Commission = 4% of her sales x = 4% of x = 0.04 * x= 0.04 x
a salesperson earns $175 per week + 0.04 x
so Amount of earning in a week = 0.04 x + 175
This week her goal is to earn no less than $525.
So amount of earning is greater than 525
0.04 x + 175 >= 525
The required expression is 0.04 x + 175 ≥ 525
