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

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
