Tv starts at 7:45pm and ends 50 mins after what time does it finish

8:35 pm

Step-by-step explanation:

60-15=45 (that is for the rest of the hour)

then 50-15=5 (that is for the next hour)

SO now you know 8:35pm

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.
