zack and are going to the fair. zack went on 3 rides and played 5 games and paid a total of $14. marissa paid $16 for 4 rides and 4 games. find the price of one ride

Respuesta :

1 ride is $3 and 1 game is $1

Price of one ride is equals to $3 for the given system of equations.

What is the system of equations?

" System of equations is a finite set of equations for which we find the common solution."

According to the question,

x represents the number of rides

y represents the number of games

Two situations are given for which we need to find the system of equations .

Situation 1: Zack went for 3 rides and played 5 games and paid $14, which represents the equation:

3x +5y = 14

⇒ 5y = 14 - 3x

⇒ y = ( 14 - 3x) / 5

Situation 2: Marissa went for 4 rides and played 4 games and paid $16, which represents the equation:

4x +4y = 16

Substitute the value y in situation 2 we get,

4x + 4[( 14 - 3x) / 5] =16

⇒ x  = 3

Hence, price of one ride is equals to $3 for the given system of equations.
