The answer to the statement made by penny that there are 4 ways to make 26 using 10 and 1 is; Not correct
She wants to make 26 with only 10's and 1's
Now, the combinations to get 26 with only 10 and 1 are as follows;
10 + 10 + 1 + 1 + 1 + 1 + 1 + 1 = 26
10 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 26
1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 26
Thus, we see that there are only 3 ways and so Penny is wrong
