rodikova [14]

Answer:the number of adults that attended the show is 248

the number of students that attended the show is 54

Step-by-step explanation:

Let x represent the number of adults that attended the show.

Let y represent the number of students that attended the show.

Total number of tickets that were sold is 302. This means that

x + y = 302

Tickets to the fashion show were $2.50 for adults and $1 for students. The receipts for all the tickets were $674. This means that

2.5x + y = 674 - - - - - - - - - 1

Substituting x = 302 - y into equation 1, it becomes

2.5(302 - y) + y = 674

755 - 2.5y + y = 674

- 2.5y + y = 674 - 755

- 1.5y = - 81

y = - 81/- 1.5

y = 54

Substituting y = 54 into x = 302 - y, it becomes

x = 302 - 54 = 248
