A total of 850 tickets were sold for a party, generating total sales of $2,050. If tickets cost $3 for couples and $2 for singles, totally how many people came to the party?

1200 people came to the party.

Step-by-step explanation:

Let x represent the number of singles tickets that were sold.

Let y represent the number of couples tickets that were sold.

A total of 850 tickets were sold for the party. It means that

x + y = 850

If tickets cost $3 for couples and $2 for singles and the total sales generated was $2050, it means that

2x + 3y = 2050- - - - - - - - - -1

Substituting x = 850 - y into equation 1, it becomes

2(850 - y) + 3y = 2050

1700 - 2y + 3y = 2050

- 2y + 3y = 2050 - 1700

y = 350

x = 850 - y = 850 - 350

x = 500

Since a couples ticket is for 2 people, it means that the number people that bought the couples tickets is

2 × 350 = 700

Therefore, the total number of people that came to the party is

500 + 700 = 1200

d? maybe

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
