Question
Monica asked each of her friends to buy a charity raffle ticket 18.How many friends did she ask?Write this information in an equation
Solution
Let's denote the number of Monica's friends as x.
According to the problem, all but 4 of her friends bought the ticket. So, the number of friends who bought the ticket is x - 4.
Each ticket costs 18 in total. So, we can write the equation as follows:
3 * (x - 4) = 18
