Identify and solve the inequality that represents how many $20 bills, n, you can withdraw from the account without going below t

Alex Ar [27]

Answer:

$100 + 20n \leq 230$

$n \leq 6$

Step-by-step explanation:

Given

$Balance = \$230.00$

$Minimum = \$100$

$Withdrawal = \$20\ each$

Required

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

$Minimum + Total\ Withdrawal \leq Available\ Balance$

Substitute values for each of these

$100 + 20n \leq 230$

Solving for n

$20n \leq 230 - 100$

$20n \leq 130$

Divide through by 20

$n \leq 6.5$

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

$n \leq 6$

GuDViN [60]

From the answer, let's assume that you can only use each number once.
So there are four slots.

_ _ _ _

For the first slot, you have a possibility of 9 numbers.

9 _ _ _

Now for the second slot, you have the possibility of 8 numbers.

9 8 _ _

Now for the third slot, you have the possibility of 7 numbers.

9 8 7 _

Now for the last slot, you have the possibility of 6 numbers.

9 8 7 6

Now multiply these numbers together and you should get 3,024.
