Can someone pls help. Been on this question for almost an hour

Step-by-step explanation:

SA = ((p x h) / 2) + b

p = perimeter of the base

h= height = 11in

b = area of the base

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.
