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.
+299 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.
\(s=43\)
+37153 s = student tix
6s + 27s − 45 = 1,374. solve for s
33s - 45 = 1374 add 45 to both sides of the equation
33s = 1419 divide both sides by 33
s = 43 number of student tix
