Answer :
0.60a + 0.80p < = 10 <== ur inequality
if u buy 9 apples....a= 9
0.60(9) + 0.80p < = 10
5.40 + 0.80p < = 10
0.80p < = 10 - 5.40
0.80p < = 4.60
p < = 4.60/0.80
p < = 5.75.....the greatest number of pears u can buy (p) is 5
if u buy 9 apples....a= 9

5.40 + 0.80p < = 10
0.80p < = 10 - 5.40
0.80p < = 4.60
p < = 4.60/0.80
p < = 5.75.....the greatest number of pears u can buy (p) is 5
