Class 5G is having a pizza party. Mrs Baker asked all the children to bring in 50c for their share of the pizza.The next day all the girls came with their 50c but Mrs Baker noticed that every girl had brought their 50c using different coins.

Whatis the most number of girls that there could be in the class?

Figure out the number of different coin combinations that will add up to 50 cents. You will just have to make a list and count them. For example

1 50 cent piece

2 quarters

5 dimes

10 nickels

50 pennies

45 pennies and 1 nickel

40 pennies and 1 dime

40 pennies and 2 nickels

30 pennies and 2 dimes

30 pennies, 1 dime and 2 nickels

30 pennies and 4 nickels

25 pennies and 1 quarter

25 pennies and 5 nickels

25 pennies, 3 nickels and 1 dime

20 pennies and three dimes

20 pennies, two dimes and two nickels

etc. etc.

There is no simple formula to plug into and solve.
