### Instruction:
Lolita has 54000 strawberry seeds. In each planting zone, 3123 seeds will be used. If she will accumulate 7 planting zones, how many strawberry seeds will remain?

### Response:
 เธอจะใช้เมล็ด 7 x 3123 = <<7*3123=21861>>21861 เมล็ด
เมล็ดที่เหลืออยู่คือ 54000 - 21861 = <<54000-21861=32139>>32139 เมล็ด.
