Bob has to hire someone to fix his garden.  A storm destroyed all 20 of his rose bushes.  He decides to replant all the rose bushes.  Each rose bush costs $150.  He also needs to pay a gardener $30 an hour, 5 hours each day for 4 days.  The final expense is 100 cubic feet of soil sold for $5 per cubic foot.  How much did the entire gardening project cost?
The roses cost 150*20=$<<150*20=3000>>3000
The gardener works 4*5=<<4*5=20>>20 hours
So the gardener charges 30*20=$<<30*20=600>>600
The soil added another 5*100=$<<5*100=500>>500
So in total the cost was 3000+600+500=$<<3000+600+500=4100>>4100
