Answer:
488
Step-by-step explanation:
Area of rectangle: 17 x 22 = 374
Area of triangle: 22 - 10 = 12
0.5(12 x 19) = 114
Add them together: 374 + 114 = 488
Answer: 60= $3.00 and 30= $4.00
x=# of $3 tickets
90-x=# of $4 tickets
$3x+$4(90-x)=$300
3x+360-4x=300
-x+360=300
-x=-360+300
-x=-60
x=60 $3 tickets
90-60=30 $4 tickets
and 
use the second expression to calculate the left-hand side of the first equation:

Add 10 to both sides if this equation to get

and divide both sides by 2

this proves that x = 17, give the two initial equations
2.5 km because 1.5 is half of 3 and half of 5 is 2.5
