A caterer charges $275 for a 3-hr event and $425 for a 5-hr event. What is the rate of change for this situation? PLEASE HELP QUICK A.) $75 per hour
B.) $85 per hour
C.) $87.50 per hour
D.) $92 per hour

a) 75 per hour

Step-by-step explanation:

The equation is y=75x+50

x is the hour and y is $

75*5=375

375+50=425

75*3=225

225+50=275

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.
