Hello there, this problem is just basic addition, here is what it would look like

Solve it and we get 78.21
Answer:
y = 5.4x + 23.5
Step-by-step explanation:
Since the service charges $23.50 for every hour, you have to multiply x by 23.5 like this: 23.5
There is a flat fee of $23.50, so you have to add 23.5 on top of that like this: 5.4x + 23.5
All of this has to add up to y; 5.4x + 23.5 = y
If you put 0 in the place of x or y, which every one you choose, it will cancel it or and you can just divide the number next to it by the answer (-20, 20). Take it one step at a time, don't try to do both at the same time.
Students on the minibus = 8
students that are boys = 5
fraction of the student that are boys = ?
we can write fraction as the numerator and denominator so here the fraction of boys students is = 5/8
this fraction means and shows that there are 5 students are boys from 8 students.
It's 28.7
Hope this helped!
