A shortage of gold causes the price of gold wire to increase by 140%. If 10 feet of gold wire previously cost $50, what is the new cost of gold wire?

Answer 1

We can find the new cost of 10 feet of gold wire by first finding 40% of 50.

40% of 50 is 20.

Now that we've done that, we can add 50 to 20 (140%), which gives us 70. 70 is the new price of 10 feet of gold wire.

Hope I helped you :)
