    This step is wrong!

    It should be: (1+3+5+...)37)=(1+37)*19 2=361The final answer should be: 3+39+19+19+361 441 This method is too complicated, and it can be counted directly by the number of a corner:

    0 corners: 5 points have 0 to 40 for a total of 41 kinds (the remainder is made up with 1 point, so there is no need to consider 1 point, the same below).

    1 corner: 5 points, 0 to 38, a total of 39 types.

    2 corners: 5 points, 0 to 36, a total of 37 types.

    20 dimes: 5 points only 0 1 kind.

    Total: 1 3 5 ...41 441 species.

    1 gross 5 points 1 point.

    19 0-2 10-0 (take a multiple of 5).

    18 0-4 20-0 (in multiples of 5).

    0 0-40 200-0 (in multiples of 5).

    Total n=1+3+5+......41=441

    The last step: 37+35+33+.11 + 9 + 7 + 5 + 3 + 1 = 361 has 1 corner 1 1 5 points need 185 1 points, 2 5 points need 180 1 points... 37 5 points require 5 points for a total of 36 types (the same below).

    There are 35 kinds of one corner of two.

    There are 33 kinds of one corner of three.

    And so on.

    The sum of three and four is 19*2 and one of the corners is split into two fives or five fives.

    Answer]: A 1 cent, 2 cent, and 5 cent coins can be used to make up a dollar, and 2 cents and 5 cents can be used to make up no more than one dollar. Thus, this question translates to:

    There are 50 2-cent coins and 20 5-cent coins, and there are many different ways to make up no more than one dollar. ”

    According to the number of 5 cents coins, there are 21 categories of counting:

    If there are 20 5-cent coins, there is obviously only one way to make them;

    If there are 19 5 cents, then the value of the 2 cents is not more than 100 5 19 5 (cents), so the 2 cents can be 0, 1 or 2, i.e. there are 3 different ways to make up the coins.

    If there are 18 cents of the 5 cents, then the value of the 2 cents does not exceed 100 5 18 10 (cents), so the 2 cents can be taken 0, 1, 2, 3, 4 or 5, that is, there are 6 different ways to make it;

    If we continue like this, we get a total of different ways to make up the following: 1 3 6 8 11 13 16 18 21 ....48 51 5 (1 3 6 8) 4 (10 20 30 40) 51 90 400 51 541 (species).

    Assuming that there are 20 pennies, there are no pennies, so there is only one way to make up them. Suppose there are 19 cents of coins with a value of 5 19 = 95 cents, so that the total value of the coins does not exceed 1 yuan = 100 cents, the value of the two cents coins cannot exceed 5 cents. Obviously, the number of pennies can be 0, 1, or 2, and there are three different ways to make up the sample.

    If we continue like this, we can see that there are different ways to make up the scale.

    1+48)+(3+46)+(6+43)+…Let high (23 + 26) + 51541 (species).

    A: There are 541 ways to make up for it.

    First use all 5 points, then reduce the number of 5 points each time, and replace them with points.

    Leave the process to yourself.
