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

Assume that you select 2 coins at random from 8 coins: 5 dimes and 3 quarters.
Vilka [71]
If the coins are selected without replacement, the probability of 2 dimes is:\frac{5}{8}\times\frac{4}{7}=\frac{5}{14}
The answer is 5/14.
Using the formula for a hypergeometric distribution, we get:
P(2\ dimes)=\frac{5C2\times3C0}{8C2}=\frac{5}{14}
