Yellowstone National Park is a popular field trip destination. This year the senior class at High School A and the senior class
at High School B both planned trips there. The senior class at High School A rented and filled 5 vans and 2 buses y with 115 students. High School B rented and filled 1 van () and 6 buses () with 163 students. Each van carried the same number of students and each bus carried the same number of students. Write equations to represent the scenario. Then, graph to find the number of students in each van and in each bus.
Each van carries 13 students and each bus carries 25 students.

Given that the senior class at High School A and the senior class at High School B both planned trips to Yellowstone, and the senior class at High School A rented and filled 5 vans and 2 buses with 115 students, while High School B rented and filled 1 van and 6 buses with 163 students, and each van carried the same number of students and each bus carried the same number of students, to determine the number of students in each van and in each bus, the following calculation must be made:
5X + 2Y = 115
1X + 6Y = 163
5X + 2Y = 115
5X + 30Y = 815
815 - 115 = 28Y
700 = 28Y
Y = 700 / 28
y = 25
1X + 6x25 = 163
1X = 163 - 150
X = 13
Therefore, each van carries 13 students and each bus carries 25 students.
The division keeps going with the remainder as 7 and 9 can only go into 70 with a 63 so to show the 7 keeps going you would have to use bar notation above 7.
Franck's answer is better (using ~), but I just wanted to point out that the conditional in yours is slightly redundant. It's easy to forget that, since you already have a boolean value, you don't need to perform a comparison in your conditional. So you could have just done this...
<span>if x
x = false;
else
x = true;
<span>end</span></span>
