If there are only a "few" different items you can use something like this:
=IF(A1="apples",25,IF(A1="grapes",35,IF(A1="pears",28,"")))
If you have many different items then you should create a 2 column lookup
table like this:
..........D..........E
1...apples.......25
2...grapes......35
3...pears........28
Then the formula would be:
=VLOOKUP(A1,D1:E3,2,0)
