A little confused on why the answer choice is A.

If Bart paid 100, then Anne pays 150.
Anne's retail price is 150 * 1.15 = 172.5
Bart's retail price is 100 * 1.85 = 185.

185 > 172.5, so shouldn't Bart's retail price be greater?

Anne pays 150 percent more for a wholesale widget than Bart pays.

Anne's retail price per widget is 15 percent greater than the wholesale price she paid.

Bart's retail price per widget is 185 percent greater than the wholesale price he paid.

Quantity A	Quantity B
Anne's retail price	Bart's retail price

The quantity in Column A is greater
The quantity in Column B is greater
The two quantities are equal
The relationship cannot be determined from the information given

To compare these two quantities, it is easiest to assign a starting value for Bart's wholesale price and then calculate each step. Let's assume Bart's wholesale price is $\mathbf{\$ 1 0 0}$.
1. Calculate Bart's Prices (Quantity B)

- Wholesale Price ( $\(W_B\)$ ): $\$ 100$
- Retail Price $\(\left(R_B\right)\)$ : The problem states his retail price is $185 %$ greater than his wholesale price.
- $185 %$ of $100=185$
- Retail Price $\(=100+185=\mathbf{2 8 5}\)$

2. Calculate Anne's Prices (Quantity A)
- Wholesale Price ( $\(W_A\)$ ): Anne pays $150 \%$ more than Bart paid.
- $150 %$ of $100=150$
- Wholesale Price $\(=100+150=250\)$

- Retail Price ( $R_A$ ): Her retail price is $15 %$ greater than her wholesale price.
- $15 %$ of 250 :
- $10 %$ is 25
- $5 %$ is 12.5
- Total increase $=37.5$
- Retail Price $\(=250+37.5=\mathbf{2 8 7 . 5}\)$
