A group of students were asked about their favorite foods. Out of the 50 students surveyed, 30 listed pizza among their favorite foods. At that rate, If 190 students were
surveyed, how many would you expect to list pizza as a favoritefood?

sorry i dont know my friend

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.
