On Tuesday, Clara bought 20 pomegranates at $20 each. At the till she got $2 off because she had a voucher. The next day, the price shot to $30 per fruit, but the store also offered a 10% discount on the total cost. Sheila took advantage of the discount and bought 20 pomegranates. What is the difference between the final prices paid for the pomegranates on the two days?
O e hiretswe diura di le 9-5=<<9-5=4>>4
O duela diura di le 4-1=<<4-1=3>>3
Ura ya ntlha e dutse 1*15=$<<1*15=15>>15
Diura tse dingwe di le 3-1=2 di a tura
Di ja  15*2=$<<15*2=30>>30 ka ura
Ka jalo diura tse 2 di dutse 2*30=$<<2*30=60>>60
Ka jalo o duela 60+15=$<<60+15=75>>75

On Tuesday, the pomegranates cost Clara 20 pomegranates * $20/pomegranates = $<<20*20=400>>400
Using the voucher, she paid $400 - $2 = $<<400-2=398>>398
On Wednesday, the pomegranates cost Sheila 20 pomegranates * $30 = $<<20*30=600>>600.
She then got a discount of 10/100 * $600 = $<<10/100*600=60>>60
Sheila ended up paying $600 - $60 = $<<600-60=540>>540
The difference is therefore $540 - $398 = $<<540-398=142>>142
