In order to solve this you need to do the original price - the sold price and figure the difference.
90-180= <span>£</span>18
therefore making it 20% of a profit sale.
M=c/at
Divide both sides by a and t to isolate m. Then the solution is just m=c/at
Answer:
If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
