Answer :
Answer:
The money each boy had after buying his ticket is $2.50.
Step-by-step explanation:
Given:
Miguel and three of his friends went to the movies. They originally had a total of $40. Each boy had the same amount of money and spent $7.50 on a ticket.
Now, to find the money each boy had after buying his ticket.
Let the money each boy had after buying his ticket be [tex]x.[/tex]
Total number of boys = 4.
Total money they had = $40.
Money each boy spent = $7.50.
Now, to write an equation:
[tex]4(x+7.50)=40[/tex]
Now, to solve the equation for getting the money each boy had after buying his ticket:
[tex]4(x+7.50)=40[/tex]
[tex]4x+30=40[/tex]
Subtracting both sides by 30 we get:
[tex]4x=10[/tex]
Dividing both sides by 4 we get:
[tex]x=\$2.50.[/tex]
Therefore, the money each boy had after buying his ticket is $2.50.
