Daniel expanded the expression as shown. What errors did he make? Select three options.

The first term should be negative.

The second term should be positive.

The last term should be -1 1/2, not -1 1/4.

He added -8 and -2 instead of multiplying -8 by -2.

He did not simplify the expression completely.

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.

1/800 is the right answer
