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

Answer:

There are 120 1st graders at Sierra Elementary School this year

Step-by-step explanation:

Let n represent the total number of 1st graders at Sierra Elementary School

Since 45% of all 1st graders at Sierra Elementary School are female students and this year there are 54 female 1st graders, 45% of n is equal to 54

→ n( $\frac{45}{100}$ ) = 54
