Answer 1

Option A

Explanation:

We are here given that Mary spent a total of $ 355.58 for a party , $200.93 on food , and an additional charge of $30.93 for each hour of party .

So the total money spent for staying at party , will be ;

`\longrightarrow \$ 355.58 - \$200.93`

`\\\longrightarrow \$ 154.65`

We can calculate the no. of hours spent at the party by dividing this amount by the rate of staying per hour at party as ;

`\\\longrightarrow ( \$ 154.65)/(\$ 30.93 / hr )`

`\\\longrightarrow 5 \ hrs .`

Hence she spent 5hrs at the party .
