Rectangle ABCD is transformed into rectangle A'B'C'D' by the following sequence of transformations. First, the figure is translated 5 units to the right and 3 units down, and then it is reflected across the y-axis. Finally, it is dilated by a scale factor of one-half.

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.
