When Natasha saves $13 more, she will have enough money to buy a basic MP3 player. The player she wants to buy costs $204, which is three times the cost of the basic player. Which equation could be used to determine n, the number of dollars Natasha has already saved? A: n + 13 = 3(204)
B: 3(n + 13) = 204
C: n + 3(13) = 204
D: 3n + 13 = 204

B

Step-by-step explanation:

Natasha already has $13 less than the price of a basic MP3 player, which is 1/3 the cost of the MP3 player she wants. Because the player she wants is $204, she would currently have $55. Therefore, the equation to represent this is B because 3(55+16) does, in fact, equal 204.
