What is the answer to this math problem

A number z plus 2.2 is at least 55. Write this word sentence as an inequality

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.

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
