A client is withdrawing $105.83. He would like $40 in $10 bills and the rest in the fewest number of bills and coins possible. S
Gennadij [26K]

Answer:

Step-by-step explanation:

The client starts with 105.83 dollars

He requests 40 of which to be subtracted in denominations of 10, meaning 4 10 dollar bills are being removed.

After this he has 65.83 more dollars to withdraw, the next biggest bill denomination is a 50, so lets subtract 50 from our account.

Now he is left with 15.83, subtract another 10 dollar bill.

That leaves us with 5.83, subtract one 5 dollar bill.

Leaving us with 0.83, subtract 3 quarters

That leaves us with 8 cents, lets subtract one nickel, leaving us with 3 cents.

Now with those 3 cents we can subtract 3 pennies.

Meaning the least amount of denominations required is:

1 50-Dollar bill

5 10-Dollar bills

1 5-Dollar bill

3 Quarters

1 Nickel

3 Pennies

The price of an American Airlines ticket to Boston increased to $600. This is a 15 percent increase. What was the old fare? Roun
FinnZ [79.3K]
The old fare was "x"
then it got bumped up by 15%, and the new price is x + 15% of x,
so.. one could say, that "x" is the 100%, then you add a 15% to
it, to get 600
thus \bf \begin{array}{ccllll}&#10;amount&\%\\&#10;\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\&#10;x&100\\&#10;600&100+15&#10;\end{array}\implies \cfrac{x}{600}=\cfrac{100}{100+15}

solve for "x"
