At the movie theatre child admission is $5.5 and an adult is $9.3. on thursday they sold 151 tickets, which was a total of $1202.90. how many adult tickets were sold that day

number of adult tickets sold on that day is 98

Step-by-step 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
