Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
There is three less than four times the number of students in Elementary School as there are in Middle School.  If the number of students in Middle school is 50, calculate the total number of students in both levels.

### Response:
 Idadi ya wanafunzi katika Shule ya Msingi ni watatu chini ya mara nne ya idadi ya wanafunzi katika Shule ya Upili: 4 * 50 wanafunzi - 3 = <<4*50-3=197>>197
Idadi jumla ya wanafunzi katika ngazi zote ni 197 + 50 = <<197+50=247>>247
