y=8x+12

y=8(32)+12
y=256+12
y=268

y=8(24)+12
y=192+12
y=204

204+268=$472

The instructor makes $472 a month.

The amount made by the instructor is the total sum of the individual amount paid by Bela and Sandra which is $472

Given the Cost equation for the lesson :

  • y = 8x + 12

Bela's cost :

y = 8(24) + 12 = $204

Sandra's cost :

y = 8(32) + 12 = $268

The total amount made by the instructor is :

  • Bela's cost + Sandra's cost

Total amount made = $204 + $268 = $472
