Lynette is selling tickets to a choral performance. She is selling senior citizen tickets and adult tickets. She sold a total of 10 tickets. Senior tickets cost $5 each and adult tickets cost $8 each. Lynette sold a total of $71 worth of tickets. If x is the number of senior tickets and y is the number of adult tickets sold, which system of linear equations models this situation?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
