Answer:
n = (204 / 3) - 13
Explanation:
In order to calculate the amount that Natasha has already saved we need to first calculate how much a basic player (B) costs. Since the player that Natasha wants is 3 times more than the basic player and costs $204 we simply divide this amount by 3.
B = 204 / 3
Now that we have the equation for the basic player we need to subtract $13 from it since it's what Natasha is missing to reach the value of the basic player.
n = (204 / 3) - 13
Now we have the equation which determines the number of dollars Natasha has already saved.
