The formula to find the x coordinate is -b/2a. If you plug in the variables

-5/2(2) = -5/4 = -1.25

x = -1.25

Now plug in x into the y equation.

y = <span>-11.125</span>

Martina buys a video game that normally costs d dollars, but it is on sale for 25% off. If the sales tax on the game is 8%, how
NNADVOKAT [17]

25% off means that they are paying 75% of the original price. Multiply d by 75%:

0.75d

Now you need to multiply the price by 1 plus the sales tax to get the total cost:

0.75d x 1.08

Simplify by multiplying 0.75 by 1.08 to get:

0.81d
