Question 63262This question is from textbook
: Jill has $3.50 in nickels and dimes. If she has 50 coins, how many of each type of coin does she have? This question is from textbook
You can put this solution on YOUR website! Let Jill have x nickels and y dimes.
Then x + y = 50 ------------------------(1)
value of x nickels = 5x
value of y dimes = 10y
==> 5x + 10y = 350
Dividing throughout by 5 we have,
==> x + 2y = 70 -----------------------(2)
Subtracting eqns (2) and (1) we get,
y = 20
Plugging in y = 20 in (1) we arrive that x = 30
Thus Jill had 30 nickels and 20 dimes.
