Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. Suppose there are twice as many student tickets sol
Arada [10]

Answer: 200 adult tickets and 400 student tickets were sold.

Step-by-step explanation:

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

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

Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. If the income from the play was $850, the expression would be

1.75x + 1.25y = 850- - - - - - - - - -1

Suppose there are twice as many student tickets sold as adult tickets. This is expressed as

y = 2x

Substituting y = 2x into equation 1, it becomes

1.75x + 1.25 × 2x = 850

1.75x + 2.5x = 850

4.25x = 850

x = 850/4.25

x = 200

y = 2x = 2 × 200

y = 400

True [87]
Well for every 9 Tuesday’s that she goes, she gets 3, so since 9•4 equals 36, then to solve you multiply 3 times 4, equals 12, so she will most likely get 12 coupons in the next year
