The flag starts at 0 and moves 8 feet right to on the number line. Then the flag moves 12 feet left to
on the number line. Then the flag moves 13 feet right to
on the number line. Nine is less than 10.

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.
