Aileen is a salesperson at Lopez Sporting Goods. She paid a monthly commission on all Little League uniforms she sells. She receives 10% of her first $2000 in sales and 12% of the balance of her sales. Last week she earned $231.20. What was the total value of the uniforms she sold?
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
Given that, Aileen receives 10% of her first $2000 in sales and 12% of the balance of her sales.
The monthly commission received for first $2000 is 10% of $2000 implies,
Thus, Aileen receives $200 for her first $2000 sales.
Given that, last week she earned $231.20.
Clearly, $231.20 is greater than $200.
That means, she must have earned more than $2000 sales.
