You go to the electronics store to buy 3 CDS. Each CD'S original cost is $9.99. You have a coupon for 10% off and the sales tax
Mrac [35]
The answer is: 28.59 (letter B)

Solution:

Total cost before tax and discount:
9.99 x 3 = 29.97
total discount: 
29.97 x 0.10 = 2.997

total cost - discount:
29.97-2.997=26.973

Tax:
26.973 X 0.06 =1.61838

Total cost plus tax:
<span>26.973 + 1.61838 =28.59138 round to only 2 decimals: 28.59</span>

-5/9x + 3x - 3 1/3 = 2/9
anygoal [31]

Step-by-step explanation:

Equations such as x + 3 = 7 are first-degree equations, since the variable has an exponent of 1. The terms to the left of an equals sign make up the left-hand member of the equation; those to the right make up the right-hand member. Thus, in the equation x + 3 = 7, the left-hand member is x + 3 and the right-hand member is 7.
