Sarah has only $180 to spend on her birthday party. If she had to pay $100 for the room and each guest cost $6 for food, how many people can she invite without going over her budget?

She can invite 13 people.

Step-by-step explanation:

Because Sarah has to pay $100 for the room, we can subtract.

$180-$100=$80.

Now that she has $80 left, we can see how many times $6 can go into $80.

$6x14=84.

This number is four more than $80, so Sarah can not invite 14 people.

But, if we do $6x13, we get $78.

$78 does not past $80 and is really close, Sarah can invite 13 people.

Final Sarah can invite 13 people without going over her budget.

I hope this helps and have a wonderful day! ;0
