Let: x = number of copies sold
We can formulate the following equation to solve for x:
1.50x - 0.9x - 600 = 0
x = 1000
Therefore, the club must sell 1000 copies to break even. Among the choices, the correct answer is A.
(5)
3x = 24 You are not supposed to subtract 3 from x, you are supposed to divide instead. So you will divide each side by 3.
So it would be:
x = 8
Initial number of students: 220
Final number of students : 180
Multiply the initial number of students (220) by the percentage change in decimal form (divided by 100) - That expression must be equal to 180.
220 x = 180
Solve for x:
x=180/220
x= 0.818181
multiply by 100
81,81 %
100%-81,81% = 18.18%
Percent change: 18.18%
