Ed owns a brake repair shop. He charges $25 to check brakes. He charges $50 for a new set of brakes. He charges $75 for labor to put a new set of brakes on.
If 5 cars came in today, and 3 of them needed a brake check and the others needed new brakes,
which equation would tell Ed how much money he made?
2(25) + 3(50 +75)
3(50) + 2 + 25 + 75
3(25) + 2(50)
3(25) + 2(50 + 75)

D. 3(25) + 2(50+75)

Step-by-step explanation:

3 cars = check brakes = $25. So, 3x25 or 3(25)

2 cars = new brakes = $50 + $75. So, 2(50+75)

Add the two semi-totals together: 3(25) + 2(50+75)

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.
