Answer:
The second one I think
Step-by-step explanation:
The increase in price is 140% of the original price.
The original price was 100% of the original price since 100% is a whole quantity.
Now the new price is 140% more than it was, so the new price is
100% + 140% of the old price.
100% + 140% = 240%
Now we find 240% of $50.
To find a percent of a number, multiply the percent by the number.
240% of $50 =
= 240% * $50
= 2.4 * $50
= $120
Answer: 10 ft of gold wire now costs $120
