Question

Please do 25 and 26 or atleast one

Answer 1

For 25, I would begin with working out the difference in price.

$450 - $360 = $90

Then, $450 is 100% of the cost, therefore we want to know how much it has decreased.

I would work out 1% of $450. [$450 / 100 = $4.50]

Now if we divide $90 (the change in cost) by $4.50, we can tell what percent of a decrease we have.

90 / 4.5 = 20

Therefore we have a 20% decrease.
