So the amount with you is $300 and the costs of the items are $200 , $50 , $15 and $15 .
total amount of things = 200+50+$15 +15 =280
so now we will minus the cost of all the things to the money u have
=300 - 280 =20 so now u are left with $20 which means that ur amount is enough for the things!
So if u have $300 you will have enough money to but things that cost $200,$50 , $15 and $15
so that was your correct answer !
i hope uve understood by now but if not then pls ask!
i hope this helps!
