Exponential growth/decay function the value of a car is $21,500. it loses 12% of its value every year. (a) write a function that represents the value y (in dollars) of the car after x years. (b) use the function to estimate the value of the car after 6 years. (round your answer to the nearest whole number)

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.
