Each game costs 1.25 and each ride costs 3.75

Step-by-step explanation:

Let,

Cost of each game = x

Cost of each ride = y

According to given statement;

5x+6y=28.75 Eqn 1

4x+3y=16.25 Eqn 2

Multiplying Eqn 2 by 2

$2(4x+3y=16.25)\\8x+6y=32.50\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(8x+6y)-(5x+6y)=32.50-28.75\\8x+6y-5x-6y=3.75\\3x=3.75$

Dividing both sides by 3

$\frac{3x}{3}=\frac{3.75}{3}\\x=1.25$

Putting x=1.25 in Eqn 1

$5(1.25)+6y=28.75\\6.25+6y=28.75\\6y=28.75-6.25\\6y=22.50$

Dividing both sides by 6

$\frac{6y}{6}=\frac{22.50}{6}\\y=3.75$

Each game costs 1.25 and each ride costs 3.75
