a) students that travel to school by car = 14
students that do not travel to school by car = 11
total number of students = 14 + 11 = 25
percentage of students that do not travel by car =
<h2>—————————————</h2>
b) 3 since we've 4 such cars in which 2 students travel , which gives us 8 students. then we've 1 car in which 3 students travel . adding them up , we get 8 + 3 = 11 students.
we've to find the number of cars that carry just 1 student.
this can be found by ,
14 - 11 = 3 cars

Answer:
51
Step-by-step explanation:
Assuming that the proportion of chocolate topping is constant.
This is a classic example of where you would need to use the process of elimination. Let's start with answer A, 3 classes.
If A were to be correct, 3 classes of 45 minutes each would be 132 greater than the amount he paid, 3 classes worth $12. We could easily express this as a math equation:
45 * 3 = 132 + (12 * 3) Then, all you would have to do is simplify:
135 = 132 + 36
135 = 168
Obviously this equation isn't true, and you can continue with answer choice B.
But wait... there's a better way. Using this starting equation, we can come up with a formula to solve for c, the number of classes. Let's take our starting equation:
45 * 3 = 132 + (12 * 3) Now, let's turn all the 3s into cs.
45c = 132 + 12c Then, using algebra, we can solve this equation.
-12c - 12c
33c = 132
33c/33 = 132/33
c = 4
And finally, we have our answer, B! I hope both methods help you in your further studies.
