Question 639174: Hey Im stumped on an alg 2 story problem;
A salesperson at a car dealership has a base salary of $25,000 per year and earns a 5% commission on total sales. How much must the salesperson sell to earn $50,000 in one year?
I don't understand what the 5% is "of." like 12 is 50% OF 24. But there is no number to base that 5% off of.

A salesperson at a car dealership has a base salary of $25,000 per year and
earns a 5% commission on total sales.
How much must the salesperson sell to earn $50,000 in one year?
:
Let a = amt that he has to sell to make 50k
:
Commis + base = 50k
.05a + 25000 = 50000
.05a = 50000 - 25000
.05a = 25000
a = 25000/.05
a = $500,000 he has to sell to make a total of 50k
