Alex sold 330 candy bars, 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 whites chocolate candy bars did alex sell?

Alex sold 330 white chocolate bars

Step-by-step explanation:

let the milk chocolate candy be x and the white chocolate candy be y. then

then 2x+3y=9901)

x+y=3302)

from eq 2) ⇒ x=330-y3)

Putting eq 3 in eq 1

2(330-y) +3y=990

660-2y+3y=990

y=990-660=3304)

Putting eq4 in eq1

2x+3(330)=990

2x+990=990

2x=990-990

2x=0

x=05)
