Question 61344
A vending machine contains nickels and dimes worth $14.50. There are 95 more nickels than dimes. How many of each coin is there?
Let # of dimes be "x"; Value of these is 10x cents
Number of nickels is "x+95" ; Value of these is 5(x+95)=5x+475 cents
EQUATION:
value + value = value
10x+5x+475=1450 cents
15x=975
x=65 (number of dimes)
x+95=160 (number of nickels)

 Also there is another word problem that has to do with an airplain flying against the wind. An airplane flew for 4hr. with a 20-km/hr. tail wind. The return flight against the same wind took 5hr. Find the speed of the plane in 
still air.
Down-wind DATA:
Whoops!   Have to go
