A certain number was multiplied by 7.4 was then taken away from the product. Finally that difference was then divided by 9, resulting in 5. Find the initial number.

The initial number is 7.

Step-by-step explanation:

Let the initial number be 'x'.

⇒ 7x-4 = 45

⇒ 7x = 49

⇒ x = 7

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
