Answer:number of adult tickets sold on that day is 98
Explanation:
Let number of child tickets sold on that day be x and
Let number of adult tickets sold on that day be y
On thursday, they sold 151 tickets. This means x+y =151 - - - - - -1
At the movie theatre child admission is $5.5 and an adult is $9.3. Total cost of tickets = $1202.90
Total Cost of child tickets =$5.5×x= 5.5x
Total Cost of adult tickets =$9.3×x= 9.3x
Total cost of tickets = total cist of child tickets + total cost of adult tickets
5.5x +9.3y = 1202.90 - - - - - -2
From equation 1, x= 151-y
Put x= 151-y in equation 2
5.5(151-y)+9.3y = 1202.90
830.5-5.5y+9.3y = 1202.90
3.8y = 372.4
y = 98
x = 151-y = 151-98 =53
Number of adult tickets sold on that day is 98
