2x + 1.5 y = 985
y = students
x = adults
x + y = 578
*-2      * -2
-2x - 2y = -1156

2x + 1.5y = 958
-2x - 2y = -1156 (add these together)

-0.5 y = -198
*-2      *-2
y = 396
x + 396 = 578
x = 182
396 students
182 adults

The cost of renting per hour = $2

For 1 hour = $2

For each additional hour, it is $1

For 2 hours = First hour + 1(additional hour)

For 2 hours = $2 + $1(1) = 2+1 = $3

For 3 hours = $2 + $1 (2) = 2+2 = $4

For 4 hours = $2 + $1(3) = 2+3 = $5
