Hi LulaBrazilia,
You can solve this question algebraically or by TESTING the Answers. Here's how you can use the answers to your advantage...
Let's TEST answer D:
If Nancy sold $4250 in furniture, she'd get $240 + 5% of $3450....
240 + .05(3450) = 240 + 172.50 = $412.50
$412.50 is not enough money to match the $450 that she actually received, which means that answer D is TOO LOW. So we need an answer that gets her more money.
Final Answer: E
It's the only answer that's left and makes sense.

Nancy's pay is made up of a base pay of $240 and a bonus of 5% of any sales above $800. Since Nancy earned $450, we know that the $230 bonus corresponds to 5% of sales above 800. The equation $230 = 5% * x would allow us to find x, the portion of sales above $800. Adding $800 to that portion will yield her total sales (800+x). The full solution below is taken from the GMATFix App.

Hi LulaBrazilia,
Here's the algebra solution:
Since Nancy gets 5% commission on sales that EXCEED $800, we have to factor that fact into the equation:
450 = 240 + .05(X - 800)
Now, it's just algebra:
210 = .05X - 40
250 = .05X
20(250) = .05X(20)
5,000 = X

We can PLUG IN THE ANSWERS, which represent the total sales.
The commission is 5%.
Since 5% = 1/20, the correct answer choice must be a multiple of 20.
Eliminate B and D.
Answer choice C: 4200
Sales that exceed 800 = 4200-800 = 3400.
Commission = 5% of 3400 = 170.
Too small.
The correct answer is E.
