algebraic expression Monica asked her friends to buy a charity raffle ticket for $3. All but 4 of her friends bought a ticket, and she raised $18. How many friends did Monica ask?

Step-by-step explanation:

Let x represent the number of friends that Monica asked to a charity raffle ticket. If all but 4 of her friends bought a ticket, it means that only 4 of her friends did not buy the charity raffle ticket. Thus, the number of her friends that bought the charity raffle ticket is

x - 4

If each ticket costs $3 and the total amount that was raised is $18, then algebraic expression representing the number of friends that Monica asked is

3(x - 4) = 18

3x - 12 = 18

3x = 18 + 12 = 30

x = 30/3 = 10

Monica asked 10 friends

do you mean add both of the equations together

because if you do the answer is 10x-5
