You can work out the percentage change and that would help you work out the rate of appreciation :)

The formula is ((new value - old value)/old value) * 100.

So you do $\frac{270,000 - 250,000}{250,000} \times 100 = 8\%$

Therefore the rate of appreciation is 8% p/a.

Brian has 16 yards of chain measured and cut at the. Hardware store. The chain will cost him 47.52$ how much is that per food? _

mojhsa [17]

3 feet= 1 yard

16*3= 48 feet.

47.52/48= 0.99

It will cost Brian $0.99 per foot.

Find the unit rate.

49.50/50= 0.99

No, it wouldn't. It would be the <em>same price

0.99=0.99 It doesn't matter which one Brian chose. </em>

I hope this helps!
