Assume A=Apple O=Orange. 10A+20O
If you have 20 oranges and 3 are bad then the percentage of bad apples is 15.
20 Percent are bananas.
20 + 50 + 20 + 10 = 50 = 150
30 or -10 if the 20 is negative.
John's price: k = 20 Jenny's price: 10+k = 20 or k = 20-10 => k = 10 Difference in price is 10 pence
2+2+2+10+5+5+5+20+20+20+20+20+20=151
thirty ate (38)
10 plus 20-2 - 11 plus 3 is equal to 20.
20 + 10 + 5 = 35
10 + 15 + 20 = 45
14.95 + 20 + 10 + 2.06 = 47.01
1 + 10 + 20 = 31
