lana wants to buy a book $6.95.how can she pay for the book using the fewest number of dollars,dimes,and pennies? using only pennies?

So Lana can give the cashier one 5 dollar bill and one 1 dollar bill so that is your 6 dollars then she can give the cashier 9 dimes and 5 pennies. Using only pennies Lana would give the cashier 695 pennies because 1 dollar is 100 pennies and so if you multiply that times 6 you get 600 then add the 95 you get 695 pennies.
I hope this helps! :D

Answer:

a) 6 Dollars, 9 Dimes and 5 Pennies

b) 695 Pennies

Step-by-step explanation:

Lana wants to buy an item for $6.95

Fewest number of dollars, dimes, nickels required:

She would need 6 dollars, 9 dimes and 5 pennies to make this payment.

It can be illustrated as:

[tex]6\times 1.00 + 9\times \frac{10}{100} + 5\times \frac{1}{100}[/tex] = 6.95

If she wants to amke payment using pennies only, then, she requires

[tex]6\times 100 + 9\times 10 + 5\times 1 = 695[/tex]

Thus, if she wishes to make the payment in pennies only, them she requires 695 pennies.
