The cost our summer school trip is $17 per students plus a $175 fee for the bus. 1) write a linear equation for the total cost of the trip? 2) what will the total cost be if 28 students go to the trip? 3) how many students attempted the trip if the total cost was $889?

Step-by-step explanation:

1)         17x + 175 = y

2)        17(28) + 175 = y

           476 + 175 = y

           651 = y

           Cost for bus and 28 students is $651

3)        889 - 175 = 714

           714/ 17 = 42

           42 students attempted the trip

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
