bernite is selling candy bars for a school fundraiser. the school paid $20 for a box of 15 king size candy bars and bernite sells them for $2 each. how much money will the school earn if bernite sells all 15 candy bars?

The school originally used $20 for the purchase of the candy.
Use the formula Y=2x to find how much money is made (y) from the number of candy bars (x)
Sub in the 15 bars for t
Y=2(15)
Y=30
Therefore the school made $10, because they earned an extra $10 in comparison to the amount they bought the candy bars for, which was $20.
Hope this helps!
