Answer:
The peak fare price is $2,2
Step-by-step explanation:
Considering
Person 1
5x + 4y= 17,40
Person 2
2x + 3y= 9,20
Isolating the x
2x= 9,20-3y
x=(9,20-3y)/2=4,6 -1,5y
x=4,6 -1,5y
Replacing in the other equation
5 (4,6 -1,5y) + 4y=17,40
23-7,5y+4y=17,40
23-17,40=7,5y-4y
5,6=3,5y
y=1,60 (this is the off peak fare)
x= 4,60-1,5y
x= 4,60-1,5*1,60
x=2,2 (this is the peak fare)
Answer:
45 I think is the answer it's my guess

Hope this helped :)
When trying to round off the answer.
Okay, the total is 69 units.
(3y)+(12)+(y+1)+(2y+3)+(11)=69
Combine like terms
6y+27=69
Subtract 27 from both sides.
69-27=42
Divide by 6 on both sides
42/6=7
y=7
Plug it into the length of AB
2(7)+3
14+3
length of AB=17
