My savings served to bought 10 candies on the store and left 650, or also could have served to buy 60 candies and had left 400. What is the price of the candies m ? 650 + 10m = 60m + 400 To know the price of the candies, we had to get the value of m: 60m - 10m = 650 - 400 50m = 250 m = 250/50 m = 5 so the price of the candies is 5, and the savings is equal to each side of the first equation: savings = 650 + 10m = 650 + 10(5) = 650 + 50 = 700 savings = 60m + 400 = 60(5) + 400 = 300 + 400 = 700 then the savings are 700
