let's first off convert the 0.6 to a fraction, and then let's keep in mind that
Standard Form of a Linear Equation
- variables must be on the left-hand-side, usually sorted in ascending order
- there must not be any fractions, just integers
- the variable "x" must not have a negative coefficient.

Step-by-step explanation:
750000 / 1500 = 500
with a 100% mark up cost it will cost p1000
The volume of the box in this problem doesn't really matter, considering that a cereal box is hollow. Assuming the surface area is 174 inches², then you can simply multiply 0.05 x 174, which is 8.7. Then put that number in the form of money to get $8.70. (seems a bit pricey for one cereal box to me ;P)
Answer:
c is marked on the diagram
c
-9 - 3 / 1 - (-7)
This can be simplified to -12/8 or -3/2.
