Final answer:
To find the total number of tickets sold so far, we can use the given information and set up an equation.
Step-by-step explanation:
To find the total number of tickets sold, we need to solve for the total based on the given percentage and the number of children's tickets sold. The problem states that 45 children's tickets have been sold, which represents 60% of the total tickets.
Since 45 children's tickets have been sold, which is 60% of the total tickets sold, we can write the equation:
45 = 0.6x
To solve for 'x', we can divide both sides of the equation by 0.6:
x = 45 / 0.6
Using a calculator, we find that the total number of tickets sold so far is 75.
