$\displaystyle x^2+5x-6=0 \\ \\ \Delta=b^2-4ac\\ \Delta=5^2-4\cdot1\cdot(-6) \\ \Delta=25+24=49 \\ \\ X_{1,2}= \frac{-b \pm \sqrt{\Delta} }{2a} \\ \\ X_1= \frac{-5-7}{2} = -\frac{12}{2} =-6 \\ \\ X_2= \frac{-5+7}{2}= \frac{2}{2} =1 \\ \\ \text{The solution set: -6 and 1}$

A supermarket reduced the price per pound whole chicken by 20%. How many pounds of chicken can now be purchased for the amount o

nignag [31]

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.
