Khampani nngwe e rekisitse dilithara di le 4000 tsa mashi mo teng ga dibotlolo kwa lebenkeleng la ga Rre Marcellus ka tlhwatlhwa ya $3.5 ka lithara. Le fa go ntse jalo, morago Rre Marcellus o ne a lemoga gore 2/5 ya mashi a a neng a a rekile a ne a feletswe ke nako e bile ga a kake a tlhola a a rekisa. O ne a busetsa mashi a a bodileng kwa khampaning mme a kopa gore a busetswe madi a gagwe. Bala gore o buseditswe madi a a kana kang. 

Mike bought 5 face masks while Johnny bought 2 more than thrice as many as Mike. How many face masks did Johnny buy?
Fa e le gore o rekile dilithara di le 4000, palo ya dilithara tse di bodileng ke 2/5 * 4000 dilithara = <<2/5*4000=1600>>1600 dilithara.
Fa lithara nngwe le nngwe e ja $3.5, mme a busetsa dilithara di le 1600 go ya go busediwa madi, palogotlhe ya madi a a a buseditsweng ke $3.5/lithara * 1600 dilithara = $<<3.5*1600=5600>>5600
#### 5600 

Thrice as many as Mike's face masks is 5 x 3 = <<5*3=15>>15.
So, Johnny bought 15 + 2 = <<15+2=17>>17 face masks.
