Math Word Problem

 
 
Reply Wed 25 May, 2016 04:23 pm
I am terrible at word problems. I can solve an equation easily, but word problems are so vague that I can't create the right equations. It is even worse when my teacher creates them him/herself. Can someone turn this word problem into an equation without solving it? Thank you!

Ly has three more dimes than nickels and twice as many quarters as dimes. The value of his coins is $9.60. How many of each kind of coin does he have?

@OkinawaOwl00,
Pick a coin and make it X. Let's use dimes.

Dimes = X

Ly has three more dimes than nickles so...

Nickles = X-3

and twice as many quarters as dimes so ...

Quarters = 2X

For money, dimes are $0.10, nickles are $0.05 and quarters are $0.25

0.10 X + .05 (X-3) + .25 (2x) = 9.60
