6 0

Answer:

2nd one and 4th one

Step-by-step explanation:

Number 2 is just putting the expression in a different order, but it is still equivalent.

The admission fee at an amusement park is $2.25 for children and $6.80 for adults. 288 people entered the park, and the admissio

Greeley [361]

Answer: Number of children = 168

Number of adults = 120

Step-by-step explanation:

Let x = Number of children and y = Number of adults

As per given,

x+y=288 (i)

2.25x+6.80y =1194 (ii)

Multiply 2.25 on both sides in (i)

2.25x+2.25y= 648 (iii)

Eliminate (iii) from (ii)

4.55y=546

$\Rightarrow y=\dfrac{546}{4.55}\\\\\Rightarrow\ y=120$

Put y= 120 in (i)

x+120=288

⇒ x=288-120

⇒ x= 168

Hence, Number of children = 168

Number of adults = 120
