For several weeks, the function f(x) = 3(4)^x represented the number of birds infected with an illness x weeks after the first birds became sick. How did the
number of sick birds change each week?

  exponential growth with a growth factor of 4

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.
