 
 <prompt> For one of di building blocks for Oakland High, dem get 5 classes. Each class dey use 2 whiteboards and each whiteboard need about 20ml of ink for one day. If ink dey cost 50 cents per ml, how much (in dollars) e go cost to use di boards for one day? <response>: ```Each ml of ink costs 50 cents so 20 ml costs 20*50 = 1000 cents
There are 2 whiteboards in each class so each class needs 2*1000 cents = 2000 cents
There are five classes in the block so they all need 5*1*2000 cents = 10000 cents
100 cents make a dollar so 10000 cents make 10000/100 = $100

The final answer: 100.```
