Answer 1

Answer: She spend $1.20 for lunch.

Explanation:

Let the total amount be 'x'.

Half of her money spend for lunch be
`(x)/(2)`

Half of her money left for a movie be
`(x)/(2)`

Amount she has now = $1.20

So, According to question, it becomes ,

`(x)/(2)=1.20\\\\x=1.20* 2\\\\x=\$2.40`

Hence, Amount she spend for lunch is
`(x)/(2)=(2.40)/(2)=\$1.20`

Therefore, she spend $1.20 for lunch.
