Answer:

Let x be the price of a raffle ticket

(x+2)*223 = 1115

x=3

Step-by-step explanation:

Let x be the price of a raffle ticket

The amount they get is now x+2 since the admin is donating 2 dollars per ticket

The sold 223 tickets

(x+2) *223 = amount raised

(x+2)*223 = 1115

Divide each side by 223

x+2 = 1115/223

x+2 = 5

Subtract 2 from each side

x+2-2 =5-2

x=3

Problem:

  • 7th-grade students decided to start fundraising money by selling raffle tickets. The administration promised to contribute $2 extra for each raffle ticket sold.

  • The 7th graders sold 223 tickets and raised a total of $1,115. Write an equation to represent this situation. Remember to define your variable.

Using variable x:

Let x is equal to,

• (x + 2) 223 = 1,115

Let's Solve it!

[tex] \quad \quad \quad \quad \tt{(x + 2) 223 = 1,115}[/tex]

[tex]\quad \quad \quad \quad \tt{ \huge x + 2 = \frac{1,115}{223} }[/tex]

[tex]\quad \quad \quad \quad \huge\tt{ x + 2 = 5 }[/tex]

Covert the 2 like this:

[tex]\quad \quad \quad \quad \huge\tt{ x = 5 - 2}[/tex]

[tex]\quad \quad \quad \quad\huge \tt{ x = 3 }[/tex]

Hence, the answer is:

[tex]\quad \quad \quad \quad \boxed{ \huge \tt{ \color{green} x = 3 }}[/tex]
