Represent using an inequality and solve
Let the number of dollars be represented by n
<em>If 1 withdrawal is $20 bill</em>
<em>n withdrawals would be $20n bills</em>
The total withdrawal and the minimum balance must be less than or equal to the available balance.
So, this gives

Substitute values for each of these

But n can not be decimal because it represents number of dollar bills , which must always be an integer.
So, we round down the value of n

Answer:
Step-by-step explanation:
Average feet per story = 1200 ÷ 50 = 24 feet
The correct answer is none of them
Using the Pythagorean theorem (a^2+b^2=c^2)
(11)^2+(14)^2=c^2
121+196=c^2
C^2=317
C=17.804
Answer: 17.804
