You must take the 248.50 and multiply it by .25 then you subtract the answer from 248.50 and end up with 186.4 then you multiply that number by .05 and add that to the 186.4 and the answer you should get is 195.69

Select the two values of x that are roots of this equation.
VMariaS [17]

Answer:

x = 2, -3

Step-by-step explanation:

x^2 + 2x- 6 = 0\\=>x^2 +3x - 2x- 6 = 0\\=>x(x+3) - 2(x +3) = 0\\=> (x-2)(x+3) = 0\\\\

(x-2)  = 0     or (x+3) = 0

x = 2  or x = -3

Thus, two values of x are x = 2, -3

48 * .5 = 24

24 the amount of money discounted off the price

Therefore it would be 48 - 24 = 24, but then comes the sales tax.

Do 24 * .045 = 1.08

1.08 is the amount of tax owed on the game so you'd do

24 + 1.08 = 25.08


A) The total cost for the game is 25.08


B) Unfortunately he is short by 8 cents and won't be able to buy the video game he wants.
