An appliance repair service charges a flat fee of $75 per service call with an additional $55 per hour. if h represents the number of hours it takes to do the repair, which function models this situation?

Our require expression will be

Step-by-step explanation:

Since we have given that

Cost of repair service charges a flat fee per service =$75

Cost of additional charges per hour = $55

Let  h be the number of hours it takes to do the repair,

So, our function models this situation like this,

(because $75 is fixed charges which occurs at the time of service call and $55 is the additional depends upon the hours as the number of hours increases it will also increase. So, it will multiply with h to get the amount according to its number of hours.)

So,our require expression will be

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.

hope this < 3

do you have the measurements?
