You can put this solution on YOUR website!
p = number of pennies
n = number of nickels
given:
(1) p+%2B+n+=+450
(2) 1%2Ap+%2B+5%2An+=+1450 (in cents)
subtract (1) from (2)
(2) 1%2Ap+%2B+5%2An+=+1450%7D%7D%0D%0A%281%29+%7B%7B%7B-p+-+n+=+-450
4n+=+1000
n+=+250
and, since
p+%2B+n+=+450
p+=+200
There are 200 pennies and 250 nickels
