25% of 40 is 10 so it would be $40+10 for the price so that should be 50. Markup=profit/cost*100
Solve for n by simplifying both sides of the equation, then isolating the variable
-2m-5n=7m-3n
+2m+3n=+2+3
-2n=9m

-2
n = 9m

Well, first, you need to set up the problem,
So, 3 1/3*2 3/5
HELPFUL HINT: Keep the fraction as a mixed number
Fractional equation converted into mixed numbers
So, 10/3*13/5= ? Can you figure out the rest? Or do you need the answer?
