Step-by-step explanation:
Increasing the side length by 5 is represented as s + 5. To get the area of a square we multiply side times side:
The area of a square is s². If we are increasing this area s² by 895, then to represent this we have s² + 895.
Put that together into an equation:
and simplify to
10s = 870 so
s = 87
Let's check that. The area before the addition to the side is 87*87 = 7569; the area after the addition of 5 cm is 92*92 = 8464. The difference is
8464 - 7569 = 895 so we did good!
Let x represent cost of each ticket and y represent cost of parking.
We have been given that the Singh's spent $335 for 5 people and parking. We can represent this information in an equation as:
We are also told that the Robinson spent $465 for 7 people and parking. We can represent this information in an equation as:
Now we will use elimination method to solve our given system of equations.
Upon subtracting equation (1) from equation (2), we will get:
Therefore, the each ticket costs $65.
Upon substituting in equation (1), we will get:
Therefore, the parking costs $10.
