Kacey was draining a pool that was 12 feet deep. she started draining the pool at 7am. by 9am, the water level was 8 feet. write an equation for the depth of the pool in relation to the time since 7am.

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.
