Answer:
System of equations,
7L + 16S = 6920 ------(1)
S = 3L + 20 --------(2)
Explanation:
Given question is incomplete; here is the complete question,
Baseball fans can buy $7 to sit in the lawn section or $16 for stadium seats. Ticket sales at last night's game totaled $6,920. The number of stadium tickets sold was 20 more than 3 times the number of lawn tickets. In order to find out how many stadium tickets were sold, Kelsey is writing a SYSTEM OF EQUATIONS. What is the second equation ?
Let the number of lawn tickets sold = L
and the number of stadium tickets sold = S
Cost of one lawn ticket = $7
Therefore, cost of L tickets = $7L
Cost of one stadium ticket = $16
Therefore, cost of S tickets = $16S
Total sales of the tickets = $(7L + 16S)
Equation for the situation will be,
7L + 16S = 6920 --------(1)
Number of stadium tickets sold were 20 more than 3 times of lawn tickets.
S = 3L + 20 -------(2)
