Question

A supermarket reduced the price per pound whole chicken by 20%. How many pounds of chicken can now be purchased for the amount of money that used to buy 20 pound of chicken

Answer 1

25 pounds

Explanation:

Let us assume that initially, 1 pound of whole chicken costs x.

So, initially 20 pounds of whole chicken costs 20x.

Now, the price is reduced by 20%.

That means that 1 pound of whole chicken now costs
`x[1-(20)/(100) ]=0.8x`

Therefore, with a 0.8x amount of money, we can now purchase 1 pound of the whole chicken.

Hence, with a 20x amount of money, we can now purchase
`(20x)/(0.8x)=25` pounds of the whole chicken.
