I'm not sure what formula to use for this story problem

Ticket sales for a play total $1,350. There were four times as many adult tickets sold as childrens tickets. The prices of tickets for adults and children are $6 and $3. How many childrens tickets were sold.

Can you help?

c = children; then adult = 4c

3c + 6(4c) = 1350

all yours to finish...

There is no one formula that fits all "story" problems. You generally have to create the formula yourself.

Ticket sales for a play total $1,350. There were four times as many adult tickets sold as childrens tickets. The prices of tickets for adults and children are $6 and $3. How many childrens tickets were sold.

Pick variables for the numbers of the adult and child tickets sold.

Write an equation for the income from the ticket sales.

Express the "adult" variable in terms of the "child" variable. (Hint: Look at the second sentence of the exercise.) Substitute this expression for the "adult" variable in the "income" equation.

Solve for the number of "child" tickets. Back-solve for the number of "adult" tickets.

If you get stuck, please reply showing how far you have gotten. Thank you.
