Question

Several years ago, Marlon bought some gold valued $970 per ounce. When he went to sell it, it was worth $1,843 per ounce. What was the percent of increase in the value of the gold?

Answer 1

`90%`

Explanation:

To find a percent increase, decrease, discount, profit, commission, mark-up etc can all be calculated using the same formula:

% Change = `("amount of change")/"original amount" xx 100%`

In case the value increased from `$970 to $1,843` which is amount of `$873`

% change = `873/970 xx 100%`

=`90%`
