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!
(40+80) + (8+2) 120+10 130 your answer would be 130 you group 40 and 80 and get the answer and then group 8 and 2 get answer to both then and then you add them together for the answer
