Explain your answer! alex sold 330 candy bars to raise money for his community basketball league. milk chocolate candy bars sold for $2 each, and white chocolate candy bars sold for $3 each. alex sold $900 worth of candy bars. how many white chocolate candy bars did alex sell?

eg. x is the number of milk chocolate candy bars, y is the number of white chocolate of candy bar

x + y = 330
2x + 3y = 900

From first equation
x + y = 330
x = 330 - y

From second equation, subtitute x with 330 - y
2x + 3y = 900
2(330-y) + 3y = 900
660 - 2y + 3y = 900
660 + y = 900
y = 900-660
y = 240

The number of white chocolate candy bars is 240

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
