 
 <prompt> John get 10 machines wey e dey work with wey e need to replace the ball bearings. Each machine dey take 30 ball bearings. Normally, e dey cost $1 per ball bearing but right now dem dey sell am for $.75. Also, because e dey buy plenty, e get 20% discount. How much money e save by buying all during the sale instead of buying one by one? <response>: ```E need replace 30*10=300 ball bearings
Di normal price na 300*1=$300
Becos of di sale e go pay only 300*.75=$225
E go get discount wey go reduce di price by another 225*.2=$45
E mean say e go pay only 225-45=$180
So e save 300-180=$120

Answer na 120.```
