Answer:
Total cost of the items is $86,69
Step-by-step explanation:
Total cost=$128.25
Discount is 35% off on the purchase
Discount =$128.25*35%= 44, 89
Final cost =$128.25-$44, 89= 83,36
Adding taxes 4%
Tax=$83,36*0,04=3,33
Final payment= $83,36+$3,33=$86,69
XZ = XY+ YZ
8.9=5.5+2c
2c= 8.9-5.5
2c=3.4
c=1.7
YZ = 2c=3.4
A and E
-3(x - y) = -3x + 3y = 3y - 3x
A. E
Hope this helps!
