Hello!
Mrs. Jones needs 3 bags of candy for every 50 of the 850 total students. The first step in solving this problem will be to calculate the number of times that 50 goes into 850:
850 ÷ 50 = 17
We have now proven that there are 17 sets of 50 students present at the school. Now, using the given fact that 3 bags of candy are needed for each set of 50 students, we can create the following equation:
3(17) = 51
We have now proven that Mrs. Jones needs a total of 51 bags of candy to feed the entire school. We are given, however, that 10 bags have already been provided. Therefore, we can use the following equation to determine the number of candy bags still needed:
51 – 10 = 41
We have now proven that Mrs. Jones still needs to acquire 41 bags of candy.
I hope this helps!
