At a school concert, the total value of tickets sold was $1,374. Student tickets sold for $6 and adult tickets sold for $9. The number of adult tickets sold was 5 less than 3 times the number of student tickets. Find the number of student tickets sold, s, by solving the equation
6s + 27s − 45 = 1,374.
OKay. Let's get started.
we will make a system of equations.
s for students.
\(6s + 27s − 45 = 1,374\)
\(27s+6s=1374+45\)-- add 45 to both sides.
\(33s=1419\)-- combine like-terms.
