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

### Instruction:
Mark is buying asphalt to pave a new section of road. The road will be 2000 feet long and 20 feet wide. Each truckload of asphalt will cover 800 square feet of road. If each truckload costs $75, and there's a 20% sales tax, how much will Mark need to pay for asphalt?

### Response:
 Kwanza tafuta eneo la barabara: futi 2000 * futi 20 = <<2000*20=40000>>40,000 futi za mraba.
Kisha ugawe eneo la barabara kwa eneo ambalo kila gari la lami litafunika: 40,000 futi za mraba / 800 futi za mraba/kila gari la lami = <<40000/800=50>>50 malori.
Kisha umultiply idadi hiyo na gharama ya kila gari la lami ili kupata gharama jumla kabla ya kodi: 50 malori * $75/malori = $<<50*75=3750>>3750.
Kisha umultiply idadi hiyo na 20% ili kupata kodi: $3750 * .2 = $<<3750*.2=750>>750.
Kisha ongeza gharama na kodi ili kupata jumla: $750 + $3750 = $<<750+3750=4500>>4500.
