Answer:

10 students

Step-by-step explanation:

Kims Charges

rent per month =$350

charges=$20 per students

let the number of students be x

and the total be y

y=mx+c

y=20x+350--------------------1

Cyndis Charges

rent per month =$400

charges=$15 per students

let the number of students be x

and the total be y

y=mx+c

y=15x+400-------------------2

Equating the two equations above to solve for x

20x+350=15x+400

20x-15x=400-350

5x=50

x=50/5

x=10

The number of students is 10 for the two of them to have the same amount
