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

Answer:

25 pounds

Step-by-step 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  $x[1-\frac{20}{100} ]=0.8x$

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 $\frac{20x}{0.8x}=25$ pounds of the whole chicken.
