I need help with someone explaining how to find the range of this! This course didn’t explain anything!

, D

Step-by-step explanation:

3 if x is greater than or equal to 1 is nothing. That leaves us with if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is , which is D.

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.

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
