Christina earns $20 per hour tutoring but will spend $30 on related expenses this month. The inequality 170≤20h−30≤200 can be used to find h, the number of hours she needs to tutor to earn between $170 and $200 this month. Which inequality represents the number of hours Christina needs to work?

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.
