Question 3

Usually, Bob's Burgers sells x burgers for p dollars each. But today, the price was lowered by 22% and as a result, 60% more burgers were sold. Which of the below represents the revenue for today's burger sales, in dollars?

Accepted Answer

Let's assume that Bob's Burgers normally sells 100 burgers for $10 each, so the total revenue would be $1000 (100 burgers x $10 per burger = $1000 total revenue). 
If the price is lowered by 22%, each burger would cost $7.80 (0.78 x $10 = $7.80). 
If 60% more burgers are sold, then the total number of burgers sold would be 160 (100 burgers + 60% more burgers = 100 burgers + 60 burgers = 160 burgers). 
The revenue for today's sales would be 160 burgers x $7.80 per burger = $1248. 
Therefore, the correct answer is C.
