Erika calculated that she would spend $115 on school supplies this year. she actually spent $82.50 on school supplies. what is erika’s percent of error?

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.

if you need just tell me and i will come to the rescue.
