Answer:
f(x) = 0.5x + 15
Step-by-step explanation:
Here, we want to get the total charge
From the question;
we have a flat rate of $15
now, $0.5 per mile for x miles will be a charge of 0.5 * x = $0.5x
We now add this to the flat fee to get the total score
That will be;
f(x) = 15 + 0.5x
The number of students would not change between before the test and after the test. 3+8 and 4+7 both = 11 so finding out how many students would equal one ratio can then be used to find how many equal 3 and 8.
If 92 students are equal to 4 in the ratio, then 1 in the ratio is worth 23 students. This is important as then when you times 23 by 7 you find out how many students there are in the regular maths class, 161 students. Plussing these two together gives you a total of 253 students.
Using this 253 you can divide it by 11 to find out how much 1 number would be in the ratio, it equals 23. Using this you can then times 23 by both 3 and 8 to find the original class sizes, 3x23 = 69, and 23x8 = 184.
Making the origional class size of the advaced class 69 studnets, and the regular maths class size 184.
