Question

PLEASE ANSWER At the city museum, child admission is  $5.70  and adult admission is  $9.30 . On Saturday,  155  tickets were sold for a total sales of  $1200.30 . How many adult tickets were sold that day?​

Answer 1

88

Explanation:

x = # of tickets for children

y = # of adult tickets

5.7x + 9.3y = 1200.3

x + y = 155

y = 155 - x

5.7x + 9.3(155 - x) = 1200.3

5.7x + 1441.5 - 9.3x = 1200.3

-3.6x = -241.2

x = 67

we want y

x + y = 155

67 + y = 155

y = 88
