one time fee of $4. Reriting a surf board at Selling Surf Stuff costs
$5 per hour with no additional fee. The hourly cost to rent a surf

inequality represents the situation when the hourly cost at Sally's Surf
Shack is less than the hourly cost at Selling Surf Stuff?

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
