Mike needed a new pair of jeans.  When he got to the mall he saw that his favorite jeans were advertised 25% off.  The original price of the jeans was $40.  How much money will Mike have left over if he pays with a $50.00 bill?
Sa ntlha, bona gore ba tla bo ba tsaya nako e e kana kang ba opela "Deck the Halls":  2 * 150 metsotsoana = <<2*150=300>>300 metsotsoana
Morago ga foo, o tseye metsotsoana eo o e tlhakanye le nako e ba tla e tsayang ba opela "Jingle Bells": 300 metsotsoana + 240 metsotsoana = <<300+240=540>>540 metsotsoana
#### 540 

The jeans cost $40 and are sale for 25% off so 40 * .25 = $<<40*.25=10.00>>10.00 discount
Take the original cost of the jeans and subtract the discount so 40-10 = $<<40-10=30.00>>30.00
Mike pays with a $50 bill and the final cost of the jeans is $30 so 50-30 = $<<50-30=20.00>>20.00 left
