In which step does a mistake first appear in simplifying the expression -2 (3a - 5) + 1.5 (6a - 10) +4(a -2) ?

Option C is incorrect

6a+ 10 + 9a - 15 - 4a - 8

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.

darn right!
