Question

At the museum, child admission is 5.80 and an adult is 9.20. On Saturday four times as many adults tickets as child tickets were sold, for a total sales of 1320.60. How many child tickets were sold that day?

Answer 1

Answer:

Number of child tickets sold = 31

Step-by-step explanation:

Let,

x be the number of child tickets sold

y be the number of adult tickets sold

According to given statement;

y = 4x      Eqn 1

5.80x + 9.20y = 1320.60     Eqn 2

Putting y=4x in Eqn 2

5.80x + 9.20(4x) = 1320.60

5.80x + 36.80x = 1320.60

42.60x = 1320.60

Dividing both sides by 42.60

$\frac{42.60x}{42.60}=\frac{1320.60}{42.60}\\x = 31$

Hence,

Number of child tickets sold = 31
