John earned 50 dollars an hour and worked 6 hours in the week.  If he spends 50 dollars on gas and wants to deposit 100 dollars in the bank, how many 25 dollar pens can he buy after he buys 5 pencils that cost 10 dollars each?
Sekolo se sengwe le se sengwe se ka nna le baithuti ba le robedi mo meleng e le supa,  seo se dira palo ya baithuti ba le 8*7 = <<8*7=56>>56.
Go na le dikolo di le tlhano tse di farologaneng tse di ka tlisang palo ya baithuti ba le 5*56 = <<5*56=280>>280. 
#### 280 

He earned $50*6=$<<50*6=300>>300
He has $300 - $100 = $<<300-100=200>>200 to spend
He spends 5 * $10 = $<<5*10=50>>50 on pencils
After buying gas and pencils he has $200 - $50 - $50 = $<<200-50-50=100>>100 to spend on pens
He can buy $100/25=<<100/25=4>>4 pens
