He has $90 in total to spend
He spent (31/45) of this money on ticket
so money spent on ticket =(31/45) *90 =2790/45 =62
Now money left with him is 90-62 =28 $
Now it says that he spent (3/7) of this remaining money at concession stand
so money spent on concession stand =(3/7)*28 =84/7 =12
Now money left with him = 28-12 =16
So money left with him is $16 but hat costs for $18
So Mr. O'Connor didnt have enough moeny to buy the hat
Let's say you have an idea that you want to present in writing. For an argument to be valid, it must have supporting evidence. An argument would just be useless if it did not have any documents or laws that would be supporting its justification. To say for example, I wanted to argue that the law of conservation of energy is not true. If I don't show actual evidence of energy being created, then that would leave me with an unclear, and most possibly invalid argument.
Instance variables are often called "fields" to help distinguish them from other variables you might use.
<h3>What are Instance variables?</h3>
Instance variables are defined within a class but outside of any method, constructor, or block.
Some key points related to Instance variables are-
- When heap space is allocated to an object, a slot is created for every instance variable value.
- Whenever an object is created with keyword 'new,' instance variables are created, and they are destroyed whenever the object is destroyed.
- Instance variables store values that need to be referenced by multiple methods, constructors, or blocks, as well as vital components of an entity's state which must be available throughout the class.
- Before or after use, instance variables could be declared just at class level.
- Variables, for example, can be given access modifiers.
- Only those methods, constructors, and blocks in the class have access to the instance variables.
