Not sure if this is for algebra but this is the algebraic solution. 1. 5x + 1y = 25 (x meaning number of nickels) (y meaning number of pennies) so 3 solutions could be, 5 nickels and 0 pennies, 4 nickels and 5 pennies, 3 nickels and 10 pennies. 2. First calculate how many days till the end of October, (31-14)= 17 days. then add 30 days for the entire month of November. Then add the 5 days that occurred in December. This will leave you with a total of 52 days.
