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

### Instruction:
A curry house sells curries that have varying levels of spice. Recently, a lot of the customers have been ordering very mild curries and the chefs have been having to throw away some wasted ingredients. To reduce cost and food wastage, the curry house starts monitoring how many ingredients are actually being used and changes their spending accordingly. The curry house needs 3 peppers for very spicy curries, 2 peppers for spicy curries, and only 1 pepper for mild curries. After adjusting their purchasing, the curry house now buys the exact amount of peppers they need. Previously, the curry house was buying enough peppers for 30 very spicy curries, 30 spicy curries, and 10 mild curries. They now buy enough peppers for 15 spicy curries and 90 mild curries. They no longer sell very spicy curries. How many fewer peppers does the curry house now buy?

### Response:
 Mgahawa wa curry awali ulikuwa unanunua pilipili 3 kwa curry kali sana * curry kali sana 30 = <<3*30=90>>90 pilipili kwa curry kali sana.
Pia walikuwa wananunua pilipili 2 kwa curry kali * curry kali 30 = <<2*30=60>>60 pilipili kwa curry kali.
Pia walikuwa wananunua pilipili 1 kwa curry zenye pilipili kidogo sana * curry zenye pilipili kidogo sana 10 = <<1*10=10>>10 pilipili kwa curry zenye pilipili kidogo sana.
Hivyo, walikuwa wananunua jumla ya pilipili 90 + 60 + 10 = <<90+60+10=160>>160.
Sasa wanunua pilipili 2 kwa curry kali * curry kali 15 = <<2*15=30>>30 pilipili kwa curry kali.
Pia sasa wanunua pilipili 1 kwa curry zenye pilipili kidogo sana * curry zenye pilipili kidogo sana 90 = <<1*90=90>>90 pilipili kwa curry zenye pilipili kidogo sana.
Hivyo, sasa wanunua jumla ya pilipili 30 + 90 = <<30+90=120>>120.
Hii ni tofauti ya pilipili 160 walizonunua awali - pilipili 120 wanazonunua sasa = <<160-120=40>>40 pilipili.
