Won ni 5 awon olopo omo oye to ni 30 ni kete, 4 awon olopo omo oye to ni 28 ni kete, ati 4 awon olopo omo oye to ni 27 ni kete. Nkan ti o ni omo kan ni awo lounch yii nbe ni $2.10, awon karotu kan, ti o ni owo $0.50, ati cookie kan, ti o ni owo $0.20. Beru owo pe owo kan fun gbogbo awon omo nbe ni owo kan fun awo lounch yii? <response>: First find the total number of students in third grade 5 classes * 30 students/class = 150 students
Then find the total number of students in fourth grade 4 classes * 28 students/class = 112 students
Then find the total number of student in fifth grade 4 classes * 27 students/class = 108 students
Now add the number of students in each grade to find the total number of students 150 students + 112 students + 108 students = 370 students
Now find the total cost of one lunch $2.10 + $0.50 + $0.20 = $2.80
Now multiply that cost by the number of students to find the total cost for the school $2.80/student * 370 students = $1036

The answer will be 1036.
