Question 409090: I need help with a word problem. This is what I have so far:
Joe has a collection of nickels and dimes that is worth $3.95. If the number of dimes was doubled and the number of nickels was increased by 21, the value of the coins would be $8.40. How many nickels and dimes does he have?

first part:
dimes value + nickles value = total amount
(value of a dime)(# of dimes) + (value of a nickle)(# of nickles) = total amount
(0.10)(# of dimes) + (0.05)(# of nickles) = 3.95
(0.10)(d) + (0.05)(n) = 3.95
so d = number of dimes we start with
n = number of nickles we start with
second part:
dimes value + nickles value = total amount
(value of a dime)(# of dimes) + (value of a nickle)(# of nickles) = total amount
(0.10)(2*d) + (0.05)(n + 21) = 8.40
because we're supposed to have double (*2 the dimes) and 21 more nickles
The two equations are then:
(0.10)(d) + (0.05)(n) = 3.95
(0.10)(2d) + (0.05)(n + 21) = 8.40
