**Steve**, Monday, October 1, 2012 at 10:38amif he paid p for the bike,

p/2 + 988 = p + 300

p/2 = 688

p = 1376

so, he sold it for 1376/2 + 988 = 1676

1676 - 1376 = 300

**Reiny**, Monday, October 1, 2012 at 10:39amlet purchase price be x

selling price = (1/2)x + 988

(-1/2)x = -688

x = 1376

bought at 1376 , sold at 1676

check:

is (1/2)1376 + 988 = 1676 ? , YES!
