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

### Instruction:
 Joe ananunua machungwa 3, maji 7, vikombe vya asali 3, na mimea 4 sokoni. Matunda yanagharimu $4.50 kila moja, maji ni senti 50 kila moja, vikombe vya asali ni $5, na mimea ni 2 kwa $18. Joe anatumia kiasi gani sokoni?


### Response:
 Joe anatumia 4.50 * 3 = <<4.50*3=13.50>>13.50 kwa machungwa.
Anatumia 7 * .50 = <<7*.50=3.50>>3.50 kwa maji.
Anatumia 3 * 5 = <<3*5=15>>15 kwa vikombe vya asali.
Anatumia 18 * 2 = <<18*2=36>>36 kwa mimea.
Joe anatumia jumla ya 13.50 + 3.50 + 15 + 36 = <<13.50+3.50+15+36=68>>68 sokoni.
